dt-bindings: display: Document dual-link LVDS display common properties

Dual-link LVDS displays receive odd pixels and even pixels separately from
dual LVDS links. One link receives odd pixels and the other receives even
pixels. Some of those displays may also use only one LVDS link to receive
all pixels, being odd and even agnostic. Document common properties for
those displays by extending LVDS display common properties defined in
lvds.yaml.
