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.

the dual LVDS links. One link receives odd pixels and the other receives
