Public bug reported:
[Impact]
WCN6856 Bluetooth doesn't work.
[Fix]
Backport firmware blobs and driver support to make it work by loading
correct firmwares.
[Test]
Bluetooth scanning and pairing work, and continue to do so after several
suspend/resume cycles.
[Where problems could occur]
The upstream version of btusb_generate_qca_nvm_name() adds several
missing le*_to_cpu() macros, so if this device was ever used on a Big
Endian system, this is a behavioral change.
