drivers: qcom: rpmh-rsc: write PDC data

Browse source 
The Power Domain Controller can be programmed to wakeup the RSC and
setup the resources back in the active state, before the processor is
woken up by a timer interrupt. The wakeup value from the timer hardware
can be copied to the PDC which has its own timer and is in an always-on
power domain. Programming the wakeup value is done through a separate
register on the RSC.
