arm64: dts: rockchip: Add power controller for RK3528

Add power-domain nodes for the power controller on RK3528.

Only PD_GPU can fully be powered down. PD_RKVDEC, PD_RKVENC, PD_VO and
PD_VPU are idle only power domains used by miscellaneous devices.

Because multiple of the miscellaneous device types currently complain
about the use of a power-domains prop, only PD_GPU is enabled.
