drm: add "auto" dithering method
There's no convenient/reliable way for drivers to both obey the dithering mode property, and to be able to attempt to provide a good default in all cases. This commit adds an "auto" method to the property which drivers can default to if they wish, whilst still allowing the user to override the choice as they do now.
