Shall we point out that a thermal zone doesn't necessarily imply a
thermal sensor?  I find it very common to assume that if you have 10
sensors, you should have 10 thermal zones.  From my point of view, a
thermal zone is an area that has similar thermal characteristics.
Therefore, the temperature of the thermal zone doesn't necessarily
have to come from on sensor, and can be defined as a combination of
the input from multiple thermal sensors.

I don't know how to put this in proper words for the documentation,
but I think it's worth hinting it here.

Cheers,
Javi
