Bug description:
[Impact]
Intel Wireless-AC 9560 requires additional driver support as well as new firmware blobs to function. Without them iwlwifi cannot correctly recognize the device on systems with Comet Lake cpu.

[Fix]
These changes are cherry-picked from either mainline kernel or backport-iwlwifi. Firmware blob iwlwifi-QuZ-a0-jf-b0-*.ucode is also necessary.

[Test]
Verified on hardware 02f0:4234 with fw rev 48.

[Regression Potential]
Low. These changes includes only necessary changes to enable Intel Wireless-AC 9560.
