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.

Qualcomm TSENS (thermal sensor device) on some devices can
|
|
be part of GCC and hence the TSENS properties can also be part
|
|
of the GCC/clock-controller node.

|
