Yeah, that's simplification from my side and assumption that at first
they designed GCC and then they copied the design to other blocks.

Several gpu/disp/cam clock controllers already include qcom,gcc.yaml, so
I would say this should not be a requirement for this patchset.

We can rename, although it always is a bit of churn - git log needs
special option, backporting is a bit trickier.
