cfg80211: pass a channel definition struct
Instead of passing a channel pointer and channel type to all functions and driver methods, pass a new channel definition struct. Right now, this struct contains just the control channel and channel type, but for VHT this will change. Also, add a small inline cfg80211_get_chandef_type() so that drivers don't need to use the _type field of the new structure all the time, which will change.
