[SRU][linux-firmware][Focal][PULL] Intermittent AX211 iwlwifi RT ucode init failed -110 at boot

[You-Sheng Yang]

BugLink: https://bugs.launchpad.net/bugs/1962515

[Impact]

AX211 might fail to load -64 firmware on some platforms.

  iwlwifi 0000:00:14.3: Failed to start RT ucode: -110

[Fix]

This can only be fixed in the firmware, and currently v5.14 kernel has
FW API 64, v5.15 has 66 and only v5.16 or above has 67.

[Test Case]

Run checkbox reboot stress tests to try trigger this issue:

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

[Where problems could occur]

The source commit originally contains 67 fw for several models, and
yet AX211, which taks iwlwifi-so-a0-gf-a0-*.ucode and its
corresponding pnvm file, is the only known problematic model
affected. This pull request imports only the needed files to
eliminate the possibility of regression as possible.
