Commit 00084f0c ("drm: bridge: thc63lvd1024: Switch to use
of_graph_get_remote_node()") simplified the thc63lvd1024 driver by
replacing hand-rolled code with a helper function. While doing so, it
created an error code path at probe time without any error message,
potentially causing probe issues that get annoying to debug. Fix it by
adding an error message.
