From: Balsam CHIHI <bchihi@xxxxxxxxxxxx>
Add thermal nodes and thermal zones for the mt8192.
The mt8192 SoC has several hotspots around the CPUs.
Specify the targeted temperature threshold to apply the mitigation
and define the associated cooling devices.

when we'll get SVS support up (which is in the LVTS-AP iospace range).
