That will consolidate the code and will allow to fix a mishandling of the trip points crossed events. In order self-encapsulate the thermal framework and prevent assumption about the indexes we remove the trip id usage in the back end drivers. As the i.MX driver is using the thermal trip generic structure, we can rely on the thermal framework to get the critical temperature instead of using the harcoded IMX_TRIP_CRITICAL index.
