[Bluetooth] Add generic driver for Bluetooth USB devices

This patch adds a new generic driver for Bluetooth USB devices. This
driver is still experimental at this point, but it is cleaner and
easier to maintain than the current Bluetooth USB driver. It is a
much better starting point for power management improvements.
