[PATCH v5 6/6] powercap: dtpm: Add RK3588 hierarchy

[Daniel Lezcano]

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 at 0, cpu at 400 and cpu at 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.
