Right, my wording was poor. The PM core's automatic attachment creates
the CX-to-GDSC parent-child relationship. Without runtime PM, however,
the GCC provider remains active and prevents CX from powering down.

I'll respin with:

Enable runtime PM for the controller, allowing CX to be powered down
once all GCC consumers have released their clocks and GDSCs.

Thanks for reviewing.
