Subject: [PATCH v9 11/15] dt-bindings: arm: rockchip: convert pmu.txt to YAML

Current dts files with 'pmu' nodes are manually verified.
In order to automate this process pmu.txt
has to be converted to yaml.

-The pmu is used to turn off and on different power domains of the SoCs
-This includes the power to the CPU cores.

-Required node properties:
-- compatible value : = "rockchip,rk3066-pmu";
-- reg : physical base address and the size of the registers window
