arm64: dts: rockchip: add thermal zones information on RK3588

Browse source

This includes the necessary device tree data to allow thermal
monitoring on RK3588(s) using the on-chip TSADC device, along with
trip points for automatic thermal management.

Each of the CPU clusters (one for the little cores and two for
the big cores) get a passive cooling trip point at 85C, which
will trigger DVFS throttling of the respective cluster upon
reaching a high temperature condition.

All zones also have a critical trip point at 115C, which will
trigger a reset.
