arm64: dts: rockchip: add rk3588 thermal sensor

Add thermal sensor IP, which allows monitoring temperatures at
seven different places in the SoC:

* Chip Center
* CPU Cluster 1 (Dual A76 "Big" Cores)
* CPU Cluster 2 (Dual A76 "Big" Cores)
* CPU Cluster 0 (Quad A55 "Little" Cores)
* Power Domain Center
* Graphics Processing Unit
* Neural Processing Unit
