HID: uhid: use generic hidinput_input_event()

Browse Source 
HID core provides the same functionality and can convert the input event
to a raw output report. We can thus drop UHID_OUTPUT_EV and rely on the
mandatory UHID_OUTPUT.

User-space wasn't able to do anything with UHID_OUTPUT_EV, anyway. They
don't have access to the report fields.

This may be received even though you haven't received UHID_OPEN, yet.
UHID_OUTPUT_EV:
UHID_OUTPUT_EV (obsolete):
Same as UHID_OUTPUT but this contains a "struct input_event" as payload. This
is called for force-feedback, LED or similar events which are received through
an input device by the HID subsystem. You should convert this into raw reports
and send them to your device similar to events of type UHID_OUTPUT.
This is no longer sent by newer kernels. Instead, HID core converts it into a
raw output report and sends it via UHID_OUTPUT.
UHID_FEATURE:
This event is sent if the kernel driver wants to perform a feature request as
