Because the generic thermal layer can not work without thermal governors, and it must load the thermal governors during its initialization. Build them into one module in this patch. This also fix a problem that the generic thermal layer does not work when CONFIG_THERMAL=m and CONFIG_THERMAL_GOV_XXX=y.

It will perform a zone name lookup and return a reference to a thermal zone device that matches the name requested. In case the zone is not found or when several zones match same name or if the required parameters are invalid, it will return the corresponding error code (ERR_PTR).
