Subject: [PATCH v2 11/14] thermal/core: Register with the trip points

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.
