soc/intel/apollolake: clear PMC registers
The clearing of the PMC registers was not being called resulting
in state persisting across reboots. This state is queried and
events are added to the eventlog like 'RTC reset' events. However,
the RTC reset event is a one time thing so it should only be logged
once. Without the clearing of the state the event was logged on
every boot.
