staging: wfx: implement start_ap/stop_ap
Currently, wfx_bss_info_changed() check interface status changes and
guess when the pattern match with an AP start and AP stop (through
wfx_update_beaconing()). It is far easier to rely on start_ap and
stop_ap callbacks provided by mac80211.
wfx_bss_info_changed() keeps only the responsibility of updating the
frame templates.
