Radar API related fixes.

* For legacy NICs, the combined RSSI should be used.
  For earlier AR5416 NICs, use control chain 0 RSSI rather than combined
  RSSI.
  For AR5416 > version 2.1, use the combined RSSI again.

* Add in a missing AR5212 HAL method (get11nextbusy) which may be called
  by radar code.

This serves no functional change for what's currently in FreeBSD.
