dm: stdio: video: Plumb the video uclass into stdio
Register video drivers with stdio so that they can be used for text output. This needs to be done explicitly for now. At some point we should be able to convert stdio itself to driver model and avoid this step. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Anatolij Gustschin <agust@denx.de>
