Bluetooth: Add driver setup stage for early init
Some drivers require a special stage for their early init. This is always specific to the driver or transport. So call back into driver to allow bringing up the device. The advantage with this stage is that the Bluetooth core is actually handling the HCI layer now. This means that command and event processing is available.
