With !CONFIG_PM_RUNTIME, this doesn't work well in the DT case, as the clocks are no longer enabled by runtime PM (some clocks may have been enabled by boot loader/reset state though). In the legacy case, this works more or less, as genpd takes over after the pm_clk domain has been initialized, which implies enabling the clocks if !CONFIG_PM_RUNTIME. Will fix...
