Bug Description

SRU Justification

[Impact]
Bluefield 3 ACPI/Window RAM configuration and related code is missing. This affects BF3 functionality w/ PKA Ring character devices being created correctly.

[Fix]
* Added ACPI config and code to detect BF3 hardware and provision the Ring devices correctly.

[Test Case]
* Tested on BF3 with mlxbf-pka module load and check the /dev/pka/<n> Ring char devices are created with correct number of entries.
* Tested with "openssl speed -engine pka -async_jobs 8 rsa" and verified the performance number show the PKA acceleration in place.

[Potential Regression]
* This fix has been tested with varieties of BF3: MB and HB cards.

This bug is awaiting verification that the linux-bluefield/5.15.0-1015.17 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-jammy' to 'verification-done-jammy'. If the problem still exists, change the tag 'verification-needed-jammy' to 'verification-failed-jammy'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
