media: rc: xbox_remote: add protocol and set timeout
The timestamps in ir-keytable -t output showed that the Xbox DVD
IR dongle decodes scancodes every 64ms. The last scancode of a
longer button press is decodes 64ms after the last-but-one which
indicates the decoder doesn't use a timeout but decodes on the last
edge of the signal.

Add a protocol with the repeat value and set the timeout in the
driver to 10ms (to have a bit of headroom for delays) so the Xbox
DVD remote performs more responsive.
