drivers: thermal: Notify only thermal zones whose trips are violated

Whenever sensor driver event notification happens, of thermal
framework notifies all thermal zones associated to that sensor for
thermal re-evaluation. In this case, thermal zones whose trips are
not violated are also forced to re-evaluate.

Check if any trip of a thermal zone is violated, then notify that
zone for thermal re-evaluation and ignore other thermal zones
whose trips are not violated.
