ath9k_htc: Fix AMPDU subframe handling

Browse source 
* Register the driver's maximum ampdu subframe limit to mac80211.
* Cleanup the target capabilities structure and fix an endian issue.
* Fix BTCOEX by sending a command to the target when the BT priority
  changes.
* Bump the required firmware version to 1.1
