thermal: int340x: Use thermal_zone_for_each_trip()
Modify int340x_thermal_update_trips() to use thermal_zone_for_each_trip()
for walking trips instead of using the trips[] table passed to the
thermal zone registration function.
For this purpose, store active trip point indices in the priv fieids of
the corresponding thermal_trip structures.
No intentional functional impact.
