ARM: rockchip: add power-management-unit 



The pmu is needed to bring up the cores during smp operations and later
also other system parts. Therefore add a node and documentation for it.

Rockchip power-management-unit:

-------------------------------



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



Example:



	pmu@20004000 {

		compatible = "rockchip,rk3066-pmu";

		reg = <0x20004000 0x100>;

	};
