Sync up mlxbf-gige driver with upstreamed version

[Asmaa Mnebhi]

SRU Justification:

[Impact]

The mlxbf-gige driver has just been upstreamed so linux-bluefield needs to be synced up with what we have upstreamed.
IMPORTANT: during testing, make sure the latest UEFI (bootloader) is loaded on top of these changes, otherwise both the gpio driver and mlxbf-gige driver will fail to load.

[Fix]

* reverted 20 commits related to the mlxbf-gige driver and 1 commit related to gpio-mlxbf2 driver since there are dependencies between them.
* Cherry-picked f92e1869d74e1acc6551256eb084a1c14a054e19 from net-next branch. The upstreamed version of the GPIO driver removed the dependency between the mlxbf-gige driver and gpio-mlxbf2 driver.
* added code that was left out of the upstreamed version. and added code that got reverted in gpio-mlxbf2.c
* updated the UEFI ACPI table to reflect the above changes (so the bootloader and the linux drivers need to be in sync)

[Test Case]

* oob_net0 coming up after several SW_RESET or reboot
* oob_net0 coming up after several powercycles
* oob_net0 coming up after pushing a new Ubuntu/CentOS/Yocto
* rmmod/modprove mlxbf_gige several times
* OOB PXE boot multiple times from UEFI menu
* automate OOB PXE boot and do reboot
* automate OOB PXE boot and do powercycle
* Test that GPIO7 reset still works on BlueSphere like boards

[Regression Potential]

Any of the test cases above could be impacted due to these changes.

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is awaiting verification that the 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-focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.

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!

Hi Asmaa. May you please verify the kernel is -proposed for focal bluefield resolves this bug? Thank you.

Hello Kelsey,

Using 5.4.0-1018-bluefield these changes were not pushed yet. We'll wait for 5.4.0-1019 and let you know whether we're able to Verify these Changes.

Thank you,
Meriton

F/bluefield 5.4.0-1019.22 is currently in -proposed and ready to test. Thank you, Meriton :)
