PM: domains: Allow a genpd consumer to require a synced power off
Some genpd providers doesn't ensure that it has turned off at hardware.
This is fine until the consumer really requires during some special
scenarios that the power domain collapse at hardware before it is
turned ON again.
An example is the reset sequence of Adreno GPU which requires that the
'gpucc cx gdsc' power domain should move to OFF state in hardware at
least once before turning in ON again to clear the internal state.
