ath5k: Implement antenna control
* Add code to support the various antenna scenarios supported by hw
* For now hardcode the default scenario (single or dual omnis with
tx/rx diversity working and tx antenna handled by session -hw keeps
track on which antenna it got ack from each ap/station and maps each
ap/station to one of the antennas-).
