Thanks for review.

Corrected in v3 :

Thanks for review.

Apologies.
The GCC does host GDSCs, so it genuinely is a power-domain provider.
Rather than disallowing #power-domain-cells, in v3 I've made it
"required" in qcom,kuno-gcc.yaml and declared #power-domain-cells = <1>
on the SoC gcc node, following qcom,sdx75-gcc.

v3:
