[Impact]
Intel Wireless-AC 9560/9462 cease to function normally with -48 rev
firmware release.

[Fix]
Two additional changes from Intel maintained backport-iwlwifi repository
are required to bring the two models back to normal.

[Test]
Verified on hardware 9462/9560 with fw rev 48.

[Regression Potential]
Low. These changes affects all iwlwifi supported devices that use
firmware blob that doesn't support iwl_geo_tx_power_profiles_cmd_v1
command. This behavior change is automatically detected, so it should
have no effect on devices other than 9462/9560 so far.
