cpu/stm32: implement periph_timer_periodic
...
Seems like the Interrupt flag for a Capture/Compare channel gets set when
- the CC-value is reached
- the timer resets before the CC value is reached.
We only want the first event and ignore the second one. Unfortunately I did
not find a way to disable the second event type, so it is filtered in software.
That is we need to
- ignore the CC-interrupts when the COUNT register register is reset
- ignore the CC-interrupts > TOP value/ARR (auto-reload register)

R12-15.

and vice versa.
Since we can only set one alarm in hardware, always set the alarm to the
closest event of the two.
