It should be most specific to least specific from left to right. I'd
rather see "qcom,sc7180-dp" dropped entirely as it will become important
to know that sc7280 has eDP and DP whereas sc7180 only has DP. We should
key that knowledge off the compatible string, so having sc7180-dp here
makes that harder, not easier.
