We want to consolidate the generic trip points code, thus preventing the different drivers to deal with the trip points after they registered them. The set_trip_temp ops will be changed regarding the above changes but first we need to rework a bit the different implementation in the drivers. The goal is to prevent using the trip id but use a trip point passed as parameter which will contain all the needed information. As we don't have the trip point passed as parameter yet, we get the trip point using the generic trip thermal framewrok APIs and use it to take exactly the same decisions. The difference with this change and the previous code is from where we get the thermal trip point (which is the same). No functional change intended.
