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...
