wifi: mt76: mt7996: add mcu command to set bssid mapping address

Browse Source 
When receiving a 4 address non-AMSDU packet, there is no bssid in the
address fields, which breaks powersave handling for 4-address peers.
Set the mcu command to use A1 as bssid when receiving 4 address
non-AMSDU packets on mt7992 and mt7990.

Also skip mt7996_mac_init_band() for invalid bands, so the command is
only sent for bands that actually exist on the device.
