thermal/intel/int340x: Replace parameter to simplify

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.
