mac80211: support VHT association
Determine the VHT channel from the AP's VHT operation IE (if present) and configure the hardware to that channel if it is supported. If channel contexts cause a channel to not be usable, try a smaller bandwidth. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
