Subject: [PATCH v3 08/12] thermal/core: Add thermal_trip in thermal_zone

The thermal trip points are properties of a thermal zone and the
different sub systems should be able to save them in the thermal zone
structure instead of having their own definition.

Give the opportunity to the drivers to create a thermal zone with
thermal trips which will be accessible directly from the thermal core
framework.
