The function adf_dbgfs_exit() was improperly named causing the build to
fail when CONFIG_DEBUG_FS=n.
Rename adf_dbgfs_cleanup() as adf_dbgfs_exit().

Move initialization of debugfs entries to a separate file.
This simplifies the exclusion of the debugfs logic in the QAT driver
when the kernel is built with CONFIG_DEBUG_FS=n.
In addition, it will allow to consolidate the addition of debugfs
entries to a single location in the code.
This implementation adds infrastructure to create (and remove) debugfs
entries at two different stages. The first, done when a device is probed,
allows to keep debugfs entries persistent between a transition in device
state (up to down or vice versa). The second, done after the initialization
phase, allows to have debugfs entries that are accessible only when
the device is up.
In addition, move the creation of debugfs entries for configuration
to the newly created function adf_dbgfs_init() and replace symbolic
permissions with octal permissions when creating the debugfs files.
This is to resolve the following warning reported by checkpatch:
WARNING: Symbolic permissions 'S_IRUSR' are not preferred. Consider using octal permissions '0400'.

Smatch complains that "dma" is uninitialized if dma_pool_alloc() fails.
This is true, but also harmless. Anyway, move the assignment after the
error checking to silence this warning.

Here is the large set of driver core changes for 6.4-rc1.
Once again, a busy development cycle, with lots of changes happening in
the driver core in the quest to be able to move "struct bus" and "struct
class" into read-only memory, a task now complete with these changes.
This will make the future rust interactions with the driver core more
"provably correct" as well as providing more obvious lifetime rules for
all busses and classes in the kernel.
The changes required for this did touch many individual classes and
busses as many callbacks were changed to take const * parameters
instead. All of these changes have been submitted to the various
subsystem maintainers, giving them plenty of time to review, and most of
them actually did so.
Other than those changes, included in here are a small set of other
things:
- kobject logging improvements
- cacheinfo improvements and updates
- obligatory fw_devlink updates and fixes
- documentation updates
- device property cleanups and const * changes
- firwmare loader dependency fixes.
All of these have been in linux-next for a while with no reported
problems.

The crypt_ctl structure must be exactly 64 bytes long to work correctly,
and it has to be a power-of-two size to allow turning the
64-bit division in crypt_phys2virt() into a shift operation, avoiding
the link failure:
ERROR: modpost: "__aeabi_uldivmod" [drivers/crypto/intel/ixp4xx/ixp4xx_crypto.ko] undefined!
The failure now shows up because the driver is available for compile
testing after the move, and a previous fix turned the more descriptive
BUILD_BUG_ON() into a link error.
Change the variably-sized dma_addr_t into the expected 'u32' type that is
needed for the hardware, and reinstate the size check for all 32-bit
architectures to simplify debugging if it hits again.

drivers/crypto/ixp4xx_crypto.c to it, along with a new Kconfig and
Makefile to contain the config and make bits.
Also add a COMPILE_TEST dependency to CRYPTO_DEV_IXP4XX so it can be
more easily compile-tested.
