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.
 
 iwlwifi
 
 * fix a lockdep warning
 
 * fix regulatory feature detection in certain firmware versions
 
 * new hardware support
 
 * fix lockdep warning
 
 * mvm: fix beacon protection checks
 
 mt76
 
 * mt7921: fix airtime reporting
 
 brcmfmac
 
 * fix a deadlock regression
