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.
