[RESEND PATCH v4 2/3] dt-bindings: display: novatek, nt35950: define ports

[Krzysztof Kozlowski]

The panel-common schema does not define what "ports" property is, so
bring the definition by referencing the panel-common-dual.yaml. Panels
can be single- or dual-link, thus require only one port at 0.
