[PATCH v1 4/4] powercap: dtpm: Add RK3588 hierarchy

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.
