V4L/DVB: IR/imon: add proper auto-repeat support

Simplified from version 1, in that hacks heisted from ati_remote2.c
aren't actually necessary, the real fix for too many repeats was
from setting too long a timer release value (200ms) on repeats in
mce mode -- this patch drops the release timeout to 33ms, matching
the input subsystem default input_dev->rep[REP_PERIOD].
