wireless-drivers fixes for v5.12

Third, and last, set of fixes for v5.12. Small fixes, iwlwifi having
most of them. brcmfmac regression caused by cfg80211 changes is the
most important here.


* fix a lockdep warning

* fix regulatory feature detection in certain firmware versions

* new hardware support

* fix lockdep warning

* mvm: fix beacon protection checks


* mt7921: fix airtime reporting


* fix a deadlock regression
iwlwifi: mvm: fix beacon protection checks

Unfortunately, since beacon protection isn't fully available
yet, we didn't notice that there are problems with it and
that the replay detection isn't working correctly. We were
relying only on mac80211, since iwl_mvm_rx_crypto() exits
when !ieee80211_has_protected(), which is of course true for
protected (but not encrypted) management frames.

Fix this to properly detect protected (but not encrypted)
management frames and handle them - we continue to only care
about beacons since for others everything can and will be
checked in mac80211.
