Implement the same thing for joysticks, so users can reduce input latency this way. This has been tested with a Logitech RumblePad 2 with jspoll=2, resulting in a polling rate of 500Hz (verified with evhz).

For a part the mapping by hid-core is accomplished by a fixup in hid-sony as the motion axes actually use vendor specific usage pages. This patch makes the DS4 use a separate input device for the motion sensors and reports acceleration data through ABS_X-ABS_Z and gyroscope data through ABS_RX-ABS_RZ. In addition it extends the event spec to allow gyroscope data through ABS_RX-ABS_RZ when INPUT_PROP_ACCELEROMETER is set. This change was suggested by Peter Hutterer during a discussion on linux-input.
