HAL updates!

* Add some more ANI spur immunity levels.
* For AR5111 radios attached to an AR5212, limit the 5GHz channels
  that are available. A later revision of the AR5111 supports the 4.9GHz
  PSB channels but right now there's no check in place for the radio
  revision.

  If someone wants PSB support on AR5212+AR5111 radios then please let
  me know and I'll add the relevant version check.
