adrian 726cd90545 A few changes to make radar detection implementable in a hal_dfs/
module.

* If sc->sc_dodfs is set to 1 by the ath_dfs_radar_enable(),
  set the relevant rx filter bit to begin receiving radar PHY
  errors. The HAL code already knows how to set the relevant
  error mask register to enable radar events.

* Add a missing call to ath_dfs_radar_enable() after ath_hal_reset()

* change ath_dfs_process_phyerr() to take a const char *buf for now,
  rather than a descriptor. This way it can get access to the packet
  buffer contents.
