General RX interrupt mitigation fixes.

* From what I can tell, interrupt mitigation doesn't mitigate RXERR events,
 only RXOK events. I'm waiting for confirmation from Atheros, but this is
 what their driver does.

* Yes, RXOK is set in AR_ISR even if it is clear in AR_IMR. So make sure
  HAL_INT_RX isn't set if interrupt mitigation is enabled.

* Add/remove comments in order to better document what is going on.
