ath9k: Add btcoex profile management support for AR9462
AR9462 chips have the capabilities to provoide bluetooth profile information. For non-AR9462 btcoex chips, the BT priority traffic was identified by periodically polling the respective registers and updated dutycycle, stomptype, etc. As AR9462 chip offers the BT profile informations, let us make use of that to update aggregation limit, dutycycle, stomptype and wieghtages.
