Arik Nemtsov 6b90deae4d TDLS: Propagate enable/disable channel-switch commands to driver 
The supplicant code does not try to control the actual channel of the
radio at any point. It simply passes the target peer and channel
parameters to the driver. It's the driver's responsibility to
periodically initiate TDLS channel-switch operations when TDLS
channel-switching is enabled.

Allow enable/disable operations to be invoked via the control interface.
