[PATCH,v2] usbhid: Add a quirk for raphnet multi-gamepad adapters

[Raphael Assenat]

The raphnet.net 4nes4snes and 2nes2snes multi-joystick adapters use a
single HID report descriptor with one report ID per controller. This
has the effect that the inputs of otherwise independent game controllers
get packed in one large joystick device.

With this patch each controller gets its own /dev/input/jsX device, 
which is more natural and less confusing than having all inputs going
to the same place.
