[PATCH v3 5/6] cfg80211: Enable GO operation on indoor channels

[Ilan Peer <ilan.peer@intel.com>]

Allow GO operation on a channel marked with IEEE80211_CHAN_INDOOR_ONLY
iff there is a user hint indicating that the platform is operating in
an indoor environment, i.e., the platform is a printer or media center
device.
