brcmfmac: rework .get_station() callback

Browse Source 
The .get_station() cfg80211 callback is used in several scenarios. In
managed mode it can obtain information about the access-point and its
BSS parameters. In managed mode it can also obtain information about
TDLS peers. In AP mode it can obtain information about connected
clients.
