Why:
For audio packet type 0x02, there are 2 Layouts:
Layout = 0 for 2 channels
and Layout = 1 for > 2 channels.
Layout will affect bandwidth check.
Currently, for HDMI FRL, Layout field isn't set and has a default value
of 0, so theoretically only 2-channel audio for audio packet type 0x02
is supported now.
How:
1. Set Layout properly according to maximum audio channel numbers for
audios with audio packet type 0x02.
2. 8ch LPCM audio is not supported for timing modes with v_active <= 576.

On Carrizo/Stoney systems we set backlight through panel_cntl, i.e.
directly via the PWM registers, if DMCU is not initialized. We
always read it back through ABM registers which leads to a
mismatch and forces atomic_commit to program the backlight
each time.
Instead make sure we use the same logic for backlight readback,
i.e. read it from panel_cntl if DMCU is not initialized.
We also need to remove some extraneous and incorrect calculations
at the end of dce_get_16_bit_backlight_from_pwm.

Testing with the photometer shows that at least Raven Ridge DCN-1.0
does not achieve more than 10 bpc effective output precision with a
16 bpc unorm surface of type SURFACE_PIXEL_FORMAT_GRPH_ABGR16161616,
unless linebuffer depth is increased from LB_PIXEL_DEPTH_30BPP to
LB_PIXEL_DEPTH_36BPP. Otherwise precision gets truncated somewhere
to 10 bpc effective depth.
Strangely this increase was not needed on Polaris11 DCE-11.2 during

fp16 framebuffers.

Add the necessary format definition, bandwidth and pixel size mappings,
prescaler setup, and pixelformat selection, following the logic
already present for SURFACE_PIXEL_FORMAT_GRPH_ARGB16161616.
The new SURFACE_PIXEL_FORMAT_GRPH_ABGR16161616 is implemented as the
old SURFACE_PIXEL_FORMAT_GRPH_ARGB16161616 format, but with swapped
red <-> green color channel, by use of the hardware xbar.
Please note that on the DCN 1/2/3 display engines, the pixelformat
in hubp and dpp setup for the old SURFACE_PIXEL_FORMAT_GRPH_ARGB16161616
and the new SURFACE_PIXEL_FORMAT_GRPH_ABGR16161616 was changed from
format id 22 to id 26. See amd/include/navi10_enum.h for the meaning
of the id's.
For format 22, the display engine read the framebuffer in 16 bpc format,
but truncated to the 12 bpc actually supported by later pipeline stages.
However, the engine took the 12 LSB of each color component for
truncation, which is incompatible with rendering at least under Vulkan,
where content is 16 bit wide, and a 12 MSB alignment would be appropriate,
if any. Format 20 for ARGB16161616_12MSB does work, but even better, we
can choose format 26 for ARGB16161616_UNORM, keeping all 16 bits around
until later stages of the display pipeline.
This allows to directly consume what the rendering hw produces under
Vulkan for swapchain format VK_FORMAT_R16G16B16A16_UNORM, as tested
with a patched version of the current AMD open-source amdvlk driver
which maps swapchain format VK_FORMAT_R16G16B16A16_UNORM onto
DRM_FORMAT_XBGR16161616.
The old id 22 would cause colorful pixeltrash to be displayed instead.
Tested under DCN-1.0 and DCE-11.2.

[WHY]
To process AUX transactions with DMUB using inbox1 and outbox1 mail boxes.
[How]
1) Added inbox1 command DMUB_CMD__DP_AUX_ACCESS to issue AUX commands
to DMUB in dc_process_dmub_aux_transfer_async(). DMUB processes AUX cmd
with DCN and sends reply back in an outbox1 message triggering an
outbox1 interrupt to driver.
2) In existing driver implementation, AUX commands are processed
synchronously by configuring DCN reg. But in DMUB AUX, driver sends an
inbox1 message and waits for a conditional variable (CV) which will be
signaled by outbox1 ISR.
3) DM will retrieve Outbox1 message and send back reply to upper layer
and complete the AUX command

[WHY]
To process AUX transactions with DMUB using inbox1 and outbox1 mail boxes.
[HOW]
1) Added inbox1 command DMUB_CMD__DP_AUX_ACCESS to issue AUX commands
to DMUB in dc_process_dmub_aux_transfer_async(). DMUB processes AUX cmd
with DCN and sends reply back in an outbox1 message triggering an
outbox1 interrupt to driver.
2) In existing driver implementation, AUX commands are processed
synchronously by configuring DCN reg. But in DMUB AUX, driver sends an
inbox1 message and waits for a conditional variable (CV) which will be
signaled by outbox1 ISR.
3) As the driver holds dal and dc locks while waiting for CV, the outbox1
ISR is registered with noMutexWait set to true, which allows ISR to run
and signal CV. This sets a constraint on ISR to not modify variables
such as dc, dmub, etc.
4) Created dmub_outbox.c with dmub_enable_outbox_notification() to enable
outbox1 mailbox.
5) New mailbox address ranges allocated for outbox1 of size DMUB_RB_SIZE.
Created dmub functions for Outbox1: dmub_dcn20_setup_out_mailbox(),
dmub_dcn20_get_outbox1_wptr() and dmub_dcn20_set_outbox1_rptr().
6) Added functions dc_stat_get_dmub_notification() and
dmub_srv_stat_get_notification() to retrieve Outbox1 message.
7) Currently, DMUB doesn't opens DDC in AUX mode before issuing AUX
transaction. A workaround is added in dce_aux_transfer_dmub_raw() to
open in DDC in AUX mode for every AUX transaction.
8) Added dc debug option enable_dmub_aux_for_legacy_ddc enable/disable
DMUB AUX. This debug option is checked dce_aux_transfer_with_retries()
to select the method to process AUX transactions.

This fixes corrupted display output in HDMI deep color
10/12 bpc mode at least as observed on AMD Mullins, DCE-8.3.
It will hopefully also provide fixes for other DCE's up to
DCE-11, assuming those will need similar fixes, but i could
not test that for HDMI due to lack of suitable hw, so viewer
discretion is advised.
dce110_stream_encoder_hdmi_set_stream_attribute() is used for
HDMI setup on all DCE's and is missing color_depth assignment.
dce110_program_pix_clk() is used for pixel clock setup on HDMI
for DCE 6-11, and is missing color_depth assignment.
Additionally some of the underlying Atombios specific encoder
and pixelclock setup functions are missing code which is in
the classic amdgpu kms modesetting path and the in the radeon
kms driver for DCE6/DCE8.
encoder_control_digx_v3() - Was missing setup code wrt. amdgpu
and radeon kms classic drivers. Added here, but untested due to
lack of suitable test hw.
encoder_control_digx_v4() - Added missing setup code.
Successfully tested on AMD mullins / DCE-8.3 with HDMI deep color
output at 10 bpc and 12 bpc.
Note that encoder_control_digx_v5() has proper setup code in place
and is used, e.g., by DCE-11.2, but this code wasn't used for deep
color setup due to the missing cntl.color_depth setup in the calling
function for HDMI.
set_pixel_clock_v5() - Missing setup code wrt. classic amdgpu/radeon
kms. Added here, but untested due to lack of hw.
set_pixel_clock_v6() - Missing setup code added. Successfully tested
on AMD mullins DCE-8.3. This fixes corrupted display output at HDMI
deep color output with 10 bpc or 12 bpc.

In set_clamp(), the comments and definitions for the COLOR_DEPTH_101010
and COLOR_DEPTH_121212 cases directly contradict the code comment which
explains how this should work, whereas the COLOR_DEPTH_888 case
is consistent with the code comments. Comment says the bitmask should
be chosen to align to the top-most 10 or 12 MSB's on a 14 bit bus, but
the implementation contradicts that: 10 bit case sets a mask for 12 bpc
clamping, whereas 12 bit case sets a mask for 14 bpc clamping.
Note that during my limited testing on DCE-8.3 (HDMI deep color)
and DCE-11.2 (DP deep color), this didn't have any obvious ill
effects, neither did fixing it change anything obvious for the
better, so this fix may be inconsequential on DCE, and just
reduce the confusion of innocent bystanders when reading the code
and trying to investigate problems with 10 bpc+ output.

Some old ASICs might not implement/require get_dig_frontend helper; in
this scenario, we can have a NULL pointer exception when we try to call
it inside vbios disable operation. For example, this situation might
happen when using Polaris12 with an eDP panel. This commit avoids this
situation by adding a specific get_dig_frontend implementation for DCEx.

Cached backlight is never being updated since panel_cntl specific
registers were moved from abm to panel_cntl.
[How]
Update cached backlight in set_abm_immediate_disable as what we used to
do. Also, update the priority of backlight restore mechanism so that
cached backlight has the highest priority since it is always correct.

[Why]
On some platforms, DMCU is no longer used. In these cases, some DMCU
memory should be completely powered off to save power.
[How]
1. Set DMCU_ERAM_MEM_PWR_FORCE to shutdown memory when DMCU is not in
use
2. Added a debug option to allow this behaviour to be turned off
3. Set all memory low power debug options to off first, to not
immediately cause problems
