mac802154: Handle basic beaconing
Implement the core hooks in order to provide the softMAC layer support
for sending beacons. Coordinators may be requested to send beacons in a
beacon enabled PAN in order for the other devices around to self
discover the available PANs automatically.
Changing the channels is prohibited while a beacon operation is
ongoing.
The implementation uses a workqueue triggered at a certain interval
depending on the symbol duration for the current channel and the
interval order provided.
Sending beacons in response to a BEACON_REQ frame (ie. answering active
scans) is not yet supported.
This initial patchset has no security support (llsec).
