wifi: cfg80211/mac80211: implement dot11ExtendedRegInfoSupport
Implement dot11ExtendedRegInfoSupport to advertise non-AP station
regulatory power capability as part of regulatory connectivity
element in (Re)Association request frames so that AP can achieve
maximum client connectivity. Control field which was interpreted
using value of 3-bits B5 to B3, now uses value of 4-bits B6 to B3 to
interpret the type of AP. Hence update IEEE80211_HE_6GHZ_OPER_CTRL_REG_INFO
to parse 4-bits control field. If older AP still updates only 3-bits
value of control field, station can still interpret the value as per
section E.2.7 of IEEE 802.11 REVme D7.0 and support the appropriate
AP type.
Also update IEEE80211_6GHZ_CTRL_REG_INDOOR_SP_AP as the value of
standard power AP is changed to 8 instead of 4 so that AP can support both
LPI AP and SP AP to maximize the connectivity with stations. For backward
compatibility, keeping value 4 as old AP by limiting it to SP AP only.
