Subject: [PATCH v2 0/3] thermal: Add support of multiple sensors

Following this comment [1], this updates thermal_of to support multiple
sensors.

This has some limitations:
- A sensor must have its own termal zone, even if it is also registered
  inside a thermal zone supporting multiple sensors.
- Only support weighted average

Changes in v2:
- Rebased on 6.7
- Seperated generic multi sensor and dt specfic code
- Simplified the code
- Drop min / max and only do weighted average (seems more adequate for IPA)
