[PATCH v3 1/3] nl80211: Extended ROC support for 40-80 MHz bandwidth

[P Praneesh <ppranees@codeaurora.org>]

Replace struct ieee80211_channel with struct cfg80211_chan_def
in remain on channel apis, because the channel width information is needed
to handle centre frequency of 80MHz, and it is available in
cfg80211_chan_def.
