HID: sony: do not rely on hid_output_raw_report
hid_out_raw_report is going to be obsoleted as it is not part of the unified HID low level transport documentation (Documentation/hid/hid-transport.txt) To do so, we need to introduce two new quirks: * HID_QUIRK_NO_OUTPUT_REPORTS_ON_INTR_EP: this quirks prevents the transport driver to use the interrupt channel to send output report (and thus force to use HID_REQ_SET_REPORT command) * HID_QUIRK_SKIP_OUTPUT_REPORT_ID: this one forces usbhid to not include the report ID in the buffer it sends to the device through HID_REQ_SET_REPORT in case of an output report This also fixes a regression introduced in commit 3a75b24949a8 (HID: hidraw: replace hid_output_raw_report() calls by appropriates ones). The hidraw API was not able to communicate with the PS3 SixAxis controllers in USB mode.
