Subject: [PATCH 1/5] arm64: dts: qcom: sc8180x: add empty mdss_edp_out
 endpoint

Follow the example of other DP controllers and also eDP controller on
SC7280 and move mdss_edp_out endpoint declaration to the SoC DTSI. This
slightly reduces the boilerplate in the platform DT files and also
reduces the difference between DP and eDP controllers.
