soc: qcom: rpmh-rsc: Attach RSC to cluster PM domain
RSC is part the CPU subsystem and powers off the CPU domains when all
the CPUs and no RPMH transactions are pending from any of the drivers.
The RSC needs to flush the 'sleep' and 'wake' votes that are critical
for saving power when all the CPUs are in idle.
Let's make RSC part of the CPU PM domains, by attaching it to the
cluster power domain. Registering for PM domain notifications, RSC
driver can be notified that the last CPU is powering down. When the last
CPU is powering down the domain, let's flush the 'sleep' and 'wake'
votes that are stored in the data buffers into the hardware and also
write next wakeup in CONTROL_TCS.
