[PATCH] cfg80211: Add new fields to wiphy structure

[Amar Singhal <asinghal@xxxxxxxxxxxxxx>]

A channel is completely defined by (oper_class, channel number) tuple,
and not just by center frequency. Operating class also tells about the
bandwidth supported by the channel. Therefore add the operating class and
channel number to the wiphy structure.
