Marcel Holtmann 22f8e9dbf6 Bluetooth: btusb: Add support for latest Apple controllers 
The latest Apple Bluetooth controllers with Broadcom chip in it have
a small design change. Instead of including a USB hub with mouse and
keyboard devices, they are now HID interfaces on the same device.

The general layout of Bluetooth devices is that interface 0 is the main
interface and interface 1 is for audio data. This design obviously moves
it to main interface 2 and audio data on interface 3.

Starting with the MacBookPro12,1 (early 2015 models) the new Broadcom
BCM943602CS cards are used which show this interface layout.
