Use the drm_of_find_panel_id() helper to decide which endpoint to use when looking up panel. This way we can support devices that have multiple possible panels, such as the aarch64 laptops.

No, I'm sorry, but that's a no-go. We can't patch every single bridge driver to support this hack. We need a solution implemented at another level that will not spread throughout the whole subsystem.
