msm: timer: Fix ONESHOT mode interrupts

MSM timers don't support an interrupt enable/disable bit.
Therefore, when the timer is free running it's possible for the
count to wrap and the match value to match again even though a
set_next_event() call hasn't been made since the last match.

Workaround the lack of an interrupt enable bit by explicitly
stopping the timer in the interrupt handler when the clockevent
is in ONESHOT mode. This should prevent any possibility of the
timer wrapping and matching more than once per set_next_event().
