Convert the i.MX8MM thermal binding to DT schema format using json-schema
Signed-off-by: Anson Huang <Anson.Huang@xxxxxxx>
---
Changes since V1:
- Add description to mention that i.MX8MM thermal driver supports
both i.MX8MM(1 sensor) and i.MX8MP(2 sensors).
- Remove ./thermal.txt reference.

+description: |
+ i.MX8MM has TMU IP to allow temperature measurement, there are
+ currently two distinct major versions of the IP that is supported
+ by a single driver. The IP versions are named v1 and v2, v1 is
+ for i.MX8MM which has ONLY 1 sensor, v2 is for i.MX8MP which has
+ 2 sensors.
