Subject: [PATCH 6/7] [stable-4.19] ARM: dts: qcom-apq8064-arrow-sd-600eval fix graph_endpoint warning

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@...0000/ports/port@...ndpoint: graph connection to node '/soc/hdmi-tx@...0000/ports/port@...ndpoint' 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.
