We're trying to switch to the of_graph way of representing connected
panels. With that, the above phandle will go away. This needs to be
replaced with:

port {
lvds_out: endpoint {
remote_endpoint = <&auo_in>;
};
};

and for the panel:

port {
auo_in: endpoint {
remote-endpoint = <&lvds_out>;
};
};
