dt-bindings: display: mediatek: simplify compatibles syntax

Lists (items) with one item should be just enum because it is shorter,
simpler and does not confuse, if one wants to add new entry with a
fallback. Convert all of them to enums. OTOH, leave unused "oneOf"
entries in anticipation of further growth of the entire binding.
