cpuidle: psci: Update init level to core_initcall()

Clients like regulators, interconnects and clocks depend on rpmh-rsc to
vote on resources and rpmh-rsc depends on psci power-domains to complete
probe. All of them are in core_initcall().

Change psci domain init level to core_initcall() to avoid probe defer from
all of the above.
