thermal: thermal_core: allow binding with limits on bind_params
When registering a thermal zone device using platform information via bind_params, the thermal framework will always perform the cdev binding using the lowest and highest limits (THERMAL_NO_LIMIT). This patch changes the data structures so that it is possible to inform what are the desired limits for each trip point inside a bind_param. The way the binding is performed is also changed so that it uses the new data structure.
