Subject[PATCH v2 3/4] arm64: dts: qcom: Disable MDSS by default for 8916/8016 devices
Date
Disable MDSS (Mobile Display Subsystem) by default in msm8916.dtsi
and only explicitly enable it in devices' DT which actually use it.

This leads to faster boot and cleaner logs for other devices,
which also won't have to explicitly disable MDSS to use framebuffer.
