Then this might not be GCC-like clock controller or gcc.yaml 
should not include power-domain-cells.

Best regards,

qcom,gcc.yaml already doesn't mark #power-domain-cells as required, so
it should be fine. See qcom,gcc-apq8064.yaml or qcom,gcc-ipq4019.yaml.

I know, I am not saying whether code is correct or not, but whether it
makes sense. If it does not have power domains, but instead interconnect
cells, maybe it should not be considered a "GCC" like block.
