dt-bindings: thermal: Make trips node optional
Even though the previous binding made it a required child node, the implementation in Linux never made it mandatory and just ignored thermal zones without trip points. This was even effectively encouraged, since the thermal core wouldn't allow a thermal sensor to probe without a thermal zone. In the case where you had a thermal device that had multiple sensors but with enough knowledge to provide trip points for only a few of them, this meant that the only way to make that driver probe was to provide a thermal zone without the trips node required by the binding. This obviously led to a fair number of device trees doing exactly that, making the initial binding requirement ineffective. Let's make it clear by dropping that requirement.
