Subject: [PATCH 2/9] arm64: dts: qcom: sc7280: Make eDP/DP controller
 default DP

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.
