[PATCH 0/2] Update init level for cmd-db, rpmh-rsc and psci cpuidle domains

[PATCH 0/2] Update init level for cmd-db, rpmh-rsc and psci cpuidle domains

[Maulik Shah]

cmd-db and rpmh-rsc are used by clients like regulators, interconnects and
clocks for resource voting. These clients are in core_initcall() while
cmd-db and rpmh-rsc are in arch_initcall(). Update init level for these
drivers also to core_initcall() to avoid unnecessary probe defer during
boot up.

Similarly psci cpuidle psci power domains are used by rpmh-rsc driver and
they are in subsys_initcall(). Update it to core_initcall().

I have picked up patch2, leaving this one for Bjorn/Konrad to manage.

[PATCH 2/2] cpuidle: psci: Update init level to core_initcall()

[Maulik Shah]

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.
