wifi: ath12k: Modify set and get antenna mac ops for single wiphy
As multiple radios are combined into a single wiphy, and
the current infrastructure supports only set/get antenna
for the wiphy, the max Tx/Rx antenna capability is advertised
during wiphy register.
Hence, When antenna set/get is received we adjust the set/get
based on max radio capability and set/get antenna accordingly.
Multi radio capability needs to introduced with interface
combination changes to support single wiphy model in cfg80211
which would help extend the wiphy specific get/set configs similar
to this to per hw level.
