Bug Description

[SRU Justification]

[Impact]

There are multiple stability issues for RTL8851B.

Issue-1:

After disabling BT and leaving it idle for a period, manually turning on the
RTL8851BE will fail.

Issue-2:

Failed to probe Bluetooth USB interface after resumed from suspend. There may be
either failure to read device descriptors:

  usb 1-14: device descriptor read/64, error -71

or tx command timeout:

  Bluetooth: hci0: Opcode 0x2041 failed: -110
  Bluetooth: hci0: command 0x2041 tx timeout

[Fix]

Upstream commit addc33924 ("rtl_bt: Update RTL8851B BT USB firmware to
0x048A_D230").

[Test Case]

$ checkbox-cli run com.canonical.plainbox::suspend/suspend_advanced_auto

[Where problems could occur]

This updates opaque firmware blobs, so it could bring further stability issues
and/or power consumption changes.

[Other Info]

While RTL8851B is only supported in oem-6.5 and linux/mantic >= 6.4, only jammy
and mantic are nominated for fix.
