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.
As we added the thermal trip points structure in the thermal zone,
let's extend the thermal zone register function to have the thermal
trip structures as a parameter and store it in the 'trips' field of
the thermal zone structure.
The thermal zone contains the trip point, we can store them directly
when registering the thermal zone. That will allow another step
forward to remove the duplicate thermal zone structure we find in the
thermal_of code.
