Matthias Reichl 172876928f 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.

267.042629: lirc protocol(unknown): scancode = 0xace
267.042665: event type EV_MSC(0x04): scancode = 0xace
267.042665: event type EV_KEY(0x01) key_down: KEY_1(0x0002)
267.042665: event type EV_SYN(0x00).
267.106625: lirc protocol(unknown): scancode = 0xace
267.106643: event type EV_MSC(0x04): scancode = 0xace
267.106643: event type EV_SYN(0x00).
267.170623: lirc protocol(unknown): scancode = 0xace
267.170638: event type EV_MSC(0x04): scancode = 0xace
267.170638: event type EV_SYN(0x00).
267.234621: lirc protocol(unknown): scancode = 0xace
267.234636: event type EV_MSC(0x04): scancode = 0xace
267.234636: event type EV_SYN(0x00).
267.298623: lirc protocol(unknown): scancode = 0xace
267.298638: event type EV_MSC(0x04): scancode = 0xace
267.298638: event type EV_SYN(0x00).
267.543345: event type EV_KEY(0x01) key_down: KEY_1(0x0002)
267.543345: event type EV_SYN(0x00).
267.570015: event type EV_KEY(0x01) key_up: KEY_1(0x0002)
267.570015: event type EV_SYN(0x00).

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.
