Bug description:
[Impact]
Bluetooth on Intel Wireless-AC 9462/9560 requires new firmware blobs to
be enabled.
[Fix]
Backport newly released firmware blobs from linux-firmware. This will
also requires minor change to the WHENCE file to resolve cherry-pick
conflicts. B/C/D would requires this explicitly and Eoan should be
rebased onto linux-firmware master branch HEAD as usual.
[Test Case]
Verified with hardware platforms with corresponding devices. Completely
power off and power on to trigger firmware reload, check from dmesg to
see if Bluetooth firmware has been correctly loaded.
[Regression Risk]
Low. This adds new binary firmware blobs that are only loaded by
targeting hardware.
