ARM: dts: rockchip: add power controller for RK3036
Add the power controller node and the correspondending qos nodes for RK3036. Also add the power-domain property to the nodes that are already present. Note: Since the regiser offsets of the axi interconnect QoS are missing in the TRM (RK3036 TRM V1.0), they have been taken from vendor kernel.
