The pmu is needed to bring up the cores during smp operations.
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>;
+ };
