[PATCH 5/5] mac80211: expose HT channel flags through debugfs

["Luis R. Rodriguez" <lrodriguez@xxxxxxxxxxx>]

Since we are not going to be exporting HT40-/+
flags for now through nl80211 we supply the channel
flags as a whole through debugfs so users/testers can
see whether or not HT40-/+ is allowed.
