I'm assuming the 0 and 1 are supposed to refer to the indexes of the hdmi and hda encoders? So it kinda looks like we want hda+hdmi cloning, but then dvo also claims to be cloneable with hdmi, but hdmi won't recipricate. So let's assume we just want hdmi+hda and nothing more and populate the possible_clones to match. The docs say the encoder itself should always be included in the possible_clones bitmask so we'll throw it in there as well. For hda we'll leave possible_clones==0 and we'll add a global fallback for that case to add the encoder itself to the bitmask since that makes life easier for most drivers.
