[SRU][N:linux-bluefield][PATCH v1 0/3] pinctrl-mlxbf3: should enable 'const pinctrl_desc' in Noble

[David Thompson]

BugLink: https://bugs.launchpad.net/bugs/2119333

SRU Justification:

[Impact]
Recent upstream changes to kernel and the BlueField-3 pin control driver,
pinctrl-mlxbf3, support the use of "const pinctrl_desc". This critical
driver structure should make use of this technique for improved stability.

[Fix]
The fix is to cherry pick the following upstream patch:
    490bfd1ca556 pinctrl: Constify static 'pinctrl_desc'
It may be required to cherry pick other upstream patches so that
everything applies cleanly.

[Test Case]
* Boot BlueField-3 platform with software containing fix
* Verify that pinctrl-mlxbf3 modules is loaded properly
* Check the kernel log via dmesg for proper messages from pinctrl subsystem
* Verify that there are no kernel faults caused by pinctrl-mlxbf3
* Reboot several times and keep checking log

[Regression Potential]
This fix is upstreamed and tested well.
