Adds the Dualshock 4 to the HID device list and enables force-feedback.

Adds a Dualshock 4 specific worker function since the Dualshock 4 needs a 
different report than the Sixaxis.

The right motor in the Dualshock 4 is variable so the full rumble value 
is now passed to the worker function and clamped there if necessary.

Thanks.

We are seeing problems with the way that DS4 interacts with Bluez (mostly
importantly how the PC and DS4 'pair'), but I believe that the kernel
stuff is OK.
