Subject: [RESEND PATCH v4 3/3] dt-bindings: display: novatek,nt36523: define ports

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, depending on the compatible, thus add
if:then:else: block narrowing ports per variant.

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