The driver calls cfg80211_get_station, which may be part of a module, so we must not enable BATMAN_ADV_BATMAN_V if BATMAN_ADV=y and CFG80211=m:

net/built-in.o: In function `batadv_v_elp_get_throughput': (text+0x5c62c): undefined reference to `cfg80211_get_station'

This clarifies the dependency to cover all combinations.
