The newly introduced mechanism for selecting eDP mode allow us to make a DisplayPort controller operate in eDP mode, but not the other way around. The qcom,sc7280-edp compatible is obviously tied to eDP, so this would not allow us to select DisplayPort-mode. Switch the compatible of the mdss_edp instance and make it eDP for the SC7280 qcard.
