HID: hid-sony: override usbhid_output_raw_report for Sixaxis

Browse source 
Override usbhid_output_raw_report in order to force output reports (sent
via hidraw_write, for instance) on the control endpoint.

The Sony Sixaxis (PS3 Controller) accepts output reports only on the
control endpoint, it silently discards them when they arrive over the
interrupt endpoint where usbhid would normally deliver them.
