Upstream commit 972910948fb6 ("ARM: dts: qcom: Remove Arrow SD600 eval board") removed this file because there are no known users, but in linux-4.19.y, we still get a compile-time warnign for it:
arch/arm/boot/dts/qcom-apq8064-arrow-sd-600eval.dtb: Warning (graph_endpoint): /soc/mdp@5100000/ports/port@3/endpoint: graph connection to node '/soc/hdmi-tx@4a00000/ports/port@0/endpoint' is not bidirectional
Address the warning by adding the remote endpoint that makes the link bidirectional. This is the same property that other boards use.
