Markus Stockhausen 8cc561dd9d clocksource/drivers/timer-rtl-otto: Do not interfere with interrupts 
[ Upstream commit c445bffbf2 ]

During normal operation the timers are reprogrammed including an
interrupt acknowledgement. This has no effect as the whole timer
is setup from scratch afterwards. Especially in an interrupt this
has already been done by rttm_timer_interrupt().

Change the behaviour as follows:

- Use rttm_disable_timer() during reprogramming
- Keep rttm_stop_timer() for all other use cases.

Downstream has already tested and confirmed a patch. See
