Dmitry Baryshkov b0ef3434da dt-bindings: clock: qcom,gcc: sort out power-domains support
On some of Qualcomm platforms the Global Clock Controller (GCC) doesn't
provide power domains. Move requirement for the '#power-domain-cells'
out of the common qcom,gcc.yaml into individual schema files. For the
platforms that do not provide power-domains, explicitly forbid having
the '#power-domain-cells' property.
