clocksource/drivers/stm32: Add oneshot mode
The stm32 timer block is able to have a counter and a comparator.
Instead of using the auto-reload register for periodic events, we switch
to oneshot mode by using the comparator register.
The timer is able to generate an interrupt when the counter overflows but
we don't want that as this counter will be use as a clocksource in the next
patches. So it is disabled by the UDIS bit of the control register.
