dt-bindings: Add missing 'additionalProperties: false' Setting 'additionalProperties: false' is frequently omitted, but is important in order to check that there aren't extra undocumented properties in a binding. Ideally, we'd just add this automatically and make this the default, but there's some cases where it doesn't work. For example, if a common schema is referenced, then properties in the common schema aren't part of what's considered for 'additionalProperties'. Also, sometimes there are bus specific properties such as 'spi-max-frequency' that go into bus child nodes, but aren't defined in the child node's schema. So let's stick with the json-schema defined default and add 'additionalProperties: false' where needed. This will be a continual review comment and game of wack-a-mole.
