thermal: gov_bang_bang: Clean up thermal_zone_trip_update()
Do the following cleanups in thermal_zone_trip_update():
* Drop the useless "zero hysteresis" message.
* Eliminate the trip_index local variable that is redundant.
* Drop 2 comments that are not useful.
* Downgrade a diagnostic message from pr_warn() to pr_debug().
* Use consistent field formatting in diagnostic messages.
