[v3,0/2] Add a generic virtual thermal sensor

Message

This series add a virtual thermal sensor.
It could be used to get a temperature using some thermal sensors.
Currently, the supported operations are max, min and avg.
The virtual sensor could be easily extended to support others operations.

Changes in v2:
- Fix some warnings / errors reported by kernel test robot
- rename some struct and functions with a more accurate name
- update the dt bindings: rename type attribute to aggregation-function
- factorize a little bit the aggregation functions
Changes in v3:
- Aggregate thermal zone instead of thermal sensors
- Use try_get_module / put_module to prevent thermal providers to be removed
- Update the bindings, to be more accurate

Alexandre Bailon (2):
  dt-bindings: Add DT bindings for the DT-based virtual sensor driver
  thermal: add a virtual sensor to aggregate temperatures
