[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.
