Subject: [PATCH] dt-bindings: thermal: Drop 'trips' node as required

It is possible to have thermal zones which don't have any trip points.
These zones in effect simply represent a temperature sensor without any
action associated with it. While the schema has always required a
'trips' node, users have existed for a long time without it. Update the
schema to match reality.
