[PATCH 3/3] arm: rockchip: rk3399: Power domain driver for rockchip.

Enable clocks and power up domains when a get on a domain is made.
This (together with initialising a couple of new clocks) helped boot a
Radxa Rock Pi 4B from SD card. It's adapted from Linux 5.15.25
and includes parameters for a dozen Rockchip SOCs, but it's only tested
on RK3399.
Some of the parameters are for SOCs not even in U-Boot yet. To save a
little space it avoids most data for SOCs not configured in the build.
It even mentions CONFIG_ROCKCHIP_RK3066 and CONFIG_ROCKCHIP_RK3366
despite those constants not being in Kconfig yet.
