Truthfully there could be some very specific circumstances where some of them would do doable, but genereally it's too much pain to deal with so we've chose not to bother. Let's use the same approach for gma500. Also the LVDS+LVDS and DSI+DSI cases probably don't really exist as there is one of each at most. This does mean we'll now leave possible_clones at 0 for these encoder types whereas previosuly we included the encoder itself in the bitmask. But that's fine as the core now treaks 0 as a special case and adds the encoder itself into the final bitmask reported to userspace.
