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

The driver + dt-binding part has been merged by Daniel Lezcano,
so let's add the DT node.
