RTC_MATCH, asserted when the content of the Alarm register is equal

AHB clock
- description: |
Reference clock: divided by the prescaler to create a time-based
strobe (typically 1 Hz) for the calendar counter. By default, the rtc
on the PolarFire SoC shares it's reference with MTIMER so this will
be a 1 MHz clock.
