The RK3588 has three CPU frequency domains, with CPUs grouped into three cpufreq policies.
Add a DTPM hierarchy for the RK3588 with one CPU node per cpufreq policy, represented by cpu@0, cpu@400 and cpu@600. Group the three CPU domains under a virtual package node attached to the RK3588 root node. Add the RK3588 compatible to the Rockchip DTPM match table to select the new hierarchy.
