[SRU][Q][PATCH v2 0/1] nouveau: don't attempt fwsec on sb on newer platforms

[Abdur Rahman]

https://bugs.launchpad.net/bugs/2154481

SRU Justification:

[Impact]

The bug causes boot failure of Questing generic kernel on systems with latest
nvidia hardware. A kernel oops due to a Null pointer dereference is observed
on bootup. The behavior is undefined in such conditions. The system may boot
but show various kinds of issues. The issue roots from the nouveau module.

[Fix]

Cherry-pick upstream commit:
e8b3627bec35 ("nouveau: don't attempt fwsec on sb on newer platforms.")

[Test Plan]

Build test and boot test for the kernel should pass for all tested hardware.

[Where problems could occur]

Since the fix touches the nouveau module, any regression in the fix commit
would end up showing undefined behavior through this module.
