Cannot identified WLAN card MT7921 in Ubunut OS with Install OS complete first OOBE Boot OS

[You-Sheng Yang]

[SRU Justification]

[Impact]

Sometimes MT7921 may not be probed due to an endless mcu reset:

  [ 5.789548] mt7921 mcu reset 0
  [ 5.790625] mt7921 rx type 0x7
  [ 5.790625] mt7921 eid 0x1 ext_eid 0x0
  [ 5.790626] mt76_rx_event eid 0x1 ext_eid 0x0

[Fix]

WiFi and Bluetooth firmware updates from mainline:
* e5a80ef8 linux-firmware: update frimware for mediatek bluetooth chip (MT7921)
* d34196f5 linux-firmware: update firmware for MT7921 WiFi device

[Test Case]

This should fix the mcu reset and wireless/bluetooh devices should be
probed successfully.

[Where problems could occur]

While there is explicit FW API for kernel version compatibility checking,
this might introduce some hidden glitches that we don't know yet.

[Other Info]

MT7921 is supported since Impish 5.13 kernel, and Impish already has the
latest Bluetooth firmware, so only the WiFi one is proposed. For oem-5.13
and oem-5.14 in Focal, both firmware updates for Bluetooth and WiFi are
required.

========== original bug report ==========

[Reproduce Steps]
1.Add the wireless card MT7921 to SUT,Install the Ubuntu OS.
2.During OOBE, Open the settings, there is no wireless settings in the panel,and the wifi cannot be used,issue occurred.

[Results]
Expected Result:The wireless settings should be exists and wifi can be used
Actual Result:The wireless settings not exists and wifi can not be used

[You-Sheng Yang (vicamo)]

MT7921 is supported starting from Impish. Impish has already the latest MT7921 bluetooth fw, but still misses the WiFi one, commit d34196f5 ("linux-firmware: update firmware for MT7921 WiFi device").

The changes made to linux-firmware 1.201.1 on impish has destablized use of a Gigabyte GC-WB867D-I REV Bluetooth 4.0/Wireless AC/B/G/N Band Dual Frequency 2.4Ghz/5.8Ghz Expansion Card. Under the new linux-firmware 1.201.1, no wifi is available under Gnome in about 80-90% of the boots. Under the prior linux-firmware 1.201 release, the wifi always appears under Gnome. Below are the differences in syslog for the broken linux-firmware 1.201.1 release...
