Bluetooth: Add controller types for BR/EDR and 802.11 AMP
With the Bluetooth 3.0 specification and the introduction of alternate MAC/PHY (AMP) support, it is required to differentiate between primary BR/EDR controllers and 802.11 AMP controllers. So introduce a special type inside HCI device for differentiation. For now all AMP controllers will be treated as raw devices until an AMP manager has been implemented.
