From: Po-Hao Huang <phhuang@xxxxxxxxxxx>
Add support of remain on channel ops. Since channel context is
required to enable multi-channel concurrent(MCC) and the current
ROC in mac80211 don't support more than 1 channel context, add this
to let P2P and other protocols relying on this work as expected.
The off-channel duration and cancel timing is purely controlled by
upper layers.
