thermal: trip: Simplify computing trip indices

A trip index can be computed right away as a difference between the
value of a trip pointer pointing to the given trip object and the
start of the trips[] table in the given thermal zone, so change
thermal_zone_trip_id() accordingly.

No intentional functional impact (except for some speedup).
