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.

Currently, thermal drivers must explicitly register their sensors to make them
available to the virtual sensor.
This doesn't seem a good solution to me and I think it would be preferable to
update the framework to register the list of each available sensors.

  dt-bindings: Add bindings for the virtual thermal sensor
  thermal: add a virtual sensor to aggregate temperatures
