pmdomain: core: Leave powered-on genpds on until late_initcall_sync
Powering-off a genpd that was on during boot, before all of its consumer
devices have been probed, is certainly prone to problems.
As a step to improve this situation, let's prevent these genpds from being
powered-off until genpd_power_off_unused() gets called, which is a
late_initcall_sync().
Note that, this still doesn't guarantee that all the consumer devices has
been probed before we allow to power-off the genpds. Yet, this should be a
step in the right direction.
