Introduce pm_runtime_get() and pm_runtime_put_sync() on the

This allows for the switching of the GDSC on/off to propagate to the parent
clock controller and consequently for any list of power-domains powering
that controller to be switched on/off.
What is the end result of this patch? Does it bring up a single PM
domain or all of them? Or should it be a part of the driver's PM
callbacks? If the CC has multiple parent PM domains, shouldn't we also
use some of them as GDSC's parents?
It brings up every PM domain in the list
clock_cc {
power-domains = <somedomain0>, <another-domain>;
};
No different to what the core code does for a single domain - except we
can actually turn the PDs off with the pm_runtime_put().
