clocksource/drivers/timer-rtl-otto: Drop set_counter function
The current counter value is a read only register. It will be
reset when writing a new target timer value with rttm_set_period().
rttm_set_counter() is essentially a noop. Drop it.
While this makes rttm_start_timer() and rttm_enable_timer() the
same functions keep both to make the established abstraction layers
for register and control functions active.
Downstream has already tested and confirmed a patch. See
