wifi: mt76: mt7996: expose per-band MAC addresses to cfg80211

Browse source

mt7996/mt7992 are single-wiphy, multi-band devices. The driver assigns
each band its own MAC address from a per-band EEPROM entry, or derives
it from the primary band's address when that entry is empty, however
only the primary band's is published as perm_addr. The per-band
addresses are not exposed to cfg80211, so consumers usually fall back
to deriving one from perm_addr.

Store each band's address in wiphy->addresses[], indexed by radio, so
cfg80211 exposes the address the hardware actually uses for that radio.
addresses[0] is the primary band and matches perm_addr, as cfg80211
requires.
