[PATCH 1/5] wpa_supplicant: Move CS supported flag to wpa_driver_capa

[Ilan Peer]

From: Andrei Otcheretianski <andrei.otcheretianski at intel.com>

Replace channel_switch_supported flag of the
wpa_driver_nl80211_data by WPA_DRIVER_FLAGS_AP_CSA inside
wpa_driver_capa.flags, it makes more sense and also can
be accessed by wpa_supplicant.
