cfg80211: introduce TDLS channel switch commands
Introduce commands to initiate and cancel TDLS channel-switching. Once
TDLS channel-switching is started, the lower level driver is responsible
for continually initiating channel-switch operations and returning to
the base (AP) channel to listen for beacons from time to time.
Upon cancellation of the channel-switch all communication between the
relevant TDLS peers will continue on the base channel.

mac80211: prepare TDLS mgmt code for channel-switch templates
Split the data-generating from the Tx-sending functionality, as we do
not want to send templates to the lower driver. Also add an optional
chandef argument to the data-generating portion. It will be used for
channel-switch templates.
