Unconditionally calling of_genpd_sync_state() causes issues on platforms with child domains as the parent domain will be turned off before the child domain was even registered during boot. This in particular is an issue for the upcoming Google gs101 support - all operations on child domains registered after the parent domain misbehave. Add a flag to the probe data to be able to sync_state conditionally only, and enable that flag on the two platforms currently supported by this driver.
