Even though this is currently describing only a reset controller I think
this binding better be talking about the "PDC Global" hardware.

Rename this qcom,pdc-global to match the compatible, and hardware name.

This is perfectly fine, in its current form it is a reset-controller.

Apart from this, the binding looks good!
