When doing scan while 6GHz channels are not enabled, the 6GHz band
is not scanned. Thus, if there are no APs on the 2GHz and 5GHz bands
(that will allow discovery of geographic location etc. that would
allow enabling the 6GHz channels) but there are non collocated APs
on 6GHz PSC channels these would never be discovered.
To overcome this, FW added support for performing passive UHB scan
in case no APs were discovered during scan on the 2GHz and 5GHz
channels.
Add support for enabling such scan when the following conditions are
met:
- 6GHz channels are supported but not enabled by regulatory.
- Station interface is not associated or less than a defined time
interval passed from the last resume or HW reset flows.
- At least 4 channels are included in the scan request
- The scan request includes the widlcard SSID.
- At least 50 minutes passed from the last 6GHz passive scan.

RF Interference Mitigation is a new feature targeted to handle the
problem of interference between DDR memory and WiFi. The role of
the driver is to configure FW with the table holding a mapping
between problematic channels/bands and the corresponding frequencies.
This patch adds RFI infrastructure and adds two debugfs hooks:
- send RFI configuration command (currently with a default table) which
will reset feature in the FW
- read the table, used by the FW (which can be a subset of the table
that driver sent).

If the firmware has support, then advertise it to the stack and
send the key down. Since we re-check the protection in the host
anyway, we don't really need to do anything on RX except that we
should drop frames that the firmware _knows_ are replay errors,
since beacon filtering might otherwise result in replays being
possible.

Using the old API with newer firmwares (starting from
iwlwifi-*-50.ucode, which implements and requires the new API version)

TX power limits as defined in the OTP assume the worst case scenario
in terms of the platform's atenna gain, but most platforms are below
that value so they can use more TX power without passing the regulatory
limit. If the platform indicates in the BIOS that it indeed has lower
gain, and the geographic location allows it, higher TX power can be
used. The driver reads the PPAG (Per-Platform Antenna Gain) data from
BIOS (if it exists), validates it and sends the appropriate command to
the FW. This flow happens once at FW init, in case of suspend/resume
there is no need to read again from BIOS as we save those values during
init, so just send the PPAG command again to FW.

In ini debug TLVs bit 24 is set. The driver relies on it in the memory
allocation for the debug configuration. This implementation is
problematic in case of a new debug TLV that is not supported yet is added
and uses bit 24. In such a scenario the driver allocate space without
using it which causes errors in the apply point enabling flow.
Solve it by explicitly checking if a given TLV is part of the list of
the supported ini debug TLVs.

Add new API and TLV for the ability to send commands in the beginning

The full flow of recovery is:
1. While loading FW, get address (from the TLV) of target buffer
to read in case of reset
2. If an error/assert happens read the address data from step 1.
3. Reset the HW and load the FW.
4. Send the data read in step 2.
5. Add station keys
6. Send notification to FW that reset flow is done.

Newer firmware versions (such as iwlwifi-8000C-34.ucode) have
introduced an API change in the SCAN_REQ_UMAC command that is not
backwards compatible. The driver needs to detect and use the new API
format when the firmware reports it, otherwise the scan command will
not work properly, causing a command timeout.
Fix this by adding a TLV that tells the driver that the new API is in
use and use the correct structures for it.

The LEDS_CMD command is only supported in some newer FW versions

(such as iwlwifi-8000C-27.ucode).
To fix this, check for a new bit in the FW capabilities TLV that tells
when the command is supported.
Note that the current version of -31.ucode in linux-firmware.git
(31.532993.0) does not have this capability bit set, so the LED won't
work, even though this version should support it. But we will update
