PWM start/stop in RTC callback.
...
I initially tried calling prst_pwm_init() in main(), and just using start/stop in
the callback, but that led to a weird behavior in the PWM output. It was set to
high after the end of the callback.
Callnig uninit/re-calling init() inside the RTC callback fixed, but more investigation
is required.

This uses the app_simple_timer library, which uses the high frequency clock
for keeping track of time.
In reality, we want to use the low frequency clock with RTC, since it's much
more power efficient and we don't need high precision.
