This neatly simplifies the code and allows us to ditch some ugly if cascades in the dp and hdmi init code (well, we need these if cascades for other stuff still, but that can be taken care of in follow-up patches). Also explain why sdvo LVDS outputs cannot be cloned: Native LVDS (and also eDP) can't be cloned, because the panel fitter is before the ouput MUX (and for cpu eDP cloning isn't possible, anyway).
