Bluetooth: Fix HCI init for 1st generation BlueFRITZ! devices

Browse Source 
The 1st generation of BlueFRITZ! devices from AVM Berlin pretend
to be HCI version 1.2 controllers, but they are not. They are simple
Bluetooth 1.1 devices.

Since this company never created any newer controllers, it is safe
to use the manufacturer ID instead of an USB quirk.
