[SRU,linux-firmware,Focal,PULL] mt7921e disappear after warm boot stress

BugLink: https://bugs.launchpad.net/bugs/1963614

[Impact]

mt7921e may not appear in the bus enumeration during warm boot stress tests.

[Fix]

This can only be fixed in the firmware.

[Test Case]

Run checkbox reboot stress tests to try trigger this issue:

  $ checkbox-cli run com.canonical.certification::stress/reboot

[Where problems could occur]

While this backports proprietary fw blob, it may bring driver
compatibility issues we cannot know in the first place.

Jammy has these already, so only Focal (for oem-5.14) is nominated.
We don't have mt7921e hardware v2.1 support in Impish 5.13 kernel.
