DVB (2390): Adds a time-delay to IR remote button presses for av7110 ir input,

- Adds a time-delay to IR remote button presses for av7110_ir input,
such that it acts more like a keyboard. A short press will be treated
as a single button press. Holding down a button on the remote will
respond like holding down a key on the keyboard, and result in a
key-repeat. This just introduces a delay between the 1st press, and
going into key-repeat so that it is possible to get a single 'up'.
