Add a fixed-up HID descriptor for the Sony motion controller and enable
controls for the LED light as well as force-feedback.

The LED is multi-colored (red, green, blue).

The motion controller has a single rumble motor so the higher of the left
and right values is used to set the speed.

 v2 fixes a nasty pointer assignment omission in the output report allocator
 and removes the 'global' LED.
