USB: convert drivers/bluetooth/* to use module_usb_driver()

This converts the drivers in drivers/bluetooth/* to use the
module_usb_driver() macro which makes the code smaller and a bit
simpler.

Added bonus is that it removes some unneeded kernel log messages about
drivers loading and/or unloading.
