rtw88: report RX power for each antenna
Report chains and chain_signal in ieee80211_rx_status.
It is useful for program such as tcpdump to see if the
antennas are well connected/placed.
8822C is able to receive CCK rates with 2 antennas, while
8822B can only use 1 antenna path to receive CCK rates.
