In the process of replacing the get_trip_* ops by the generic trip points, the current code has an 'override' property to add another indirection to a different ops. Rework this approach to prevent this indirection and make the code ready for the generic trip points conversion. Actually the get_temp() is different regarding the platform, so it is pointless to add a new set of ops but just create dynamically the ops at init time.
