    exynos: video: Enable stdout env var backward compatibility for LCD · 3296eeff

    Commit bb5930d5 ("exynos: video: Convert several boards to driver
    model for video") converted the Exynos Chromebooks machines to use DM
    for video, but this breaks backward compatibility with the stdout env
    var since now stdout is expected to be "vidconsole" instead of "lcd".
    
    This causes display to not work when updating u-boot on these boards
    if the old stdout env var is used. Since these are consumer devices,
    there's no easy way to have a serial console so users may be confused
    thinking that u-boot failed to boot, or in the best case will need to
    update the stdout env var blindly to make the display to work again.
    
    There's a CONFIG_VIDCONSOLE_AS_LCD config option to workaround this,
    so enable it in the Chromebooks' default configuration files to allow
    users to change their stdout env var before the workaround is removed.
