Subject: [PATCH] dt-bindings: chrome: google,cros-ec-type: restrict allowed properties

Describe exactly what properties are allowed in Google Chrome OS EC Type
C port, so the schema can properly validate the DTS.  Existing DTS
defines always connectors with unit addresses, not a sole "connector"
child.
