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.
