[Impact]

Mediatek MT7921 may fail to resume from runtime suspend can cause chip
reset.

  mt7921e 0000:02:00.0: PM: failed to resume async: error -110
  mt7921e 0000:02:00.0: chip reset

[Fix]

This is fixed with both bluetooth and WiFi firmware upgrade to
upstream commit 094d7adc1136 ("linux-firmware: update firmware for
MT7921 WiFi device") and commit 1e744b85cd4c ("linux-firmware: update
firmware for mediatek bluetooth chip(MT7921)").

[Test Case]

This can be triggered by checkbox warm reset stress test:

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

[Where problems could occur]

This imports fixes requiring both kernel driver and proprietary firmware
updates, the firmware part might cause instability or so.

[Other Info]

This is fixed in firmware, so it's affecting all kernels supporting
MT7921, which means F/H/I/J.
