Subject: [PATCH 2/5] arm64: dts: qcom: sc8280xp: add empty mdss*_dp*_out
endpoints
Follow the example of other DP controllers and also eDP controller on
SC7280 and move all mdss[01]_dp[0123]_out endpoints 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.
