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).
