[PATCH v2 1/3] dt-bindings: thermal: samsung: Add tmu-name and sensor-index-ranges properties

[Shin Son]

The exynosautov920 TMU requires per-sensor interrupt enablement
for its critical trip points.
Add a DT property to the Samsung thermal bindings
to support this requirement:

- **samsung,hw-sensor-indices**: Defines the sensors currently
                                 mapped to the TMU hardware.
				 Indices not listed are absent or fused off

Additionally, add myself to the bindings' maintainers list, as I plan
to actively work on the exynosautov920 TMU support and handle further
updates in this area.
