[PATCH v2 1/2] dt-bindings: display: novatek,nt35950: define ports

[Krzysztof Kozlowski]

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

Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski at linaro.org>

Changes since v1:
1. Rework to add ports to device schema, not to panel-common.
