Support for adding DT based thermal zones at runtime

One Line Summary

During a recent project I encountered an issue where I needed support for thermal
zones that get instantiated by a devicetree overlay. In our specific case we had temperature sensors
on a daughtercard that is swap-able. I haven't found a good solution on how to make the current
of-thermal code work with runtime added thermal-zones, (assumption is all thermal zones present at boot)
and was wondering if people have clever ideas.
