wifi: cfg80211: remove cfg80211_inform_single_bss_frame_data()

This function pretty much does what cfg80211_inform_single_bss_data()
already does, except on a frame data. But we can call the other one,
after populating the inform_data more completely, so we don't need to
do everything twice.

This also uncovered a few bugs:
 * the 6 GHz power type checks were only done in this function, move
   (and rename from 'uhb') those;
 * the chains/chain_signal information wasn't used in the latter,
   add that
