The AM62x SoC supports three temperature ranges:
* A: -40 to 105C - Extended Industrial
* H: 0 to 95C - Commercial
* I: -40 to 125C - Automotive
Add device tree include files to adjust the alert and critical trip
points in k3-am62-thermal based on the temperature grade.
Passive trip points are always set 10C below critical.
