video: Fix video on coreboot with the copy buffer
The copy buffer, if enabled, prevents booting from coreboot correctly, since no memory is allocated for it. Allow it to fall back to disabled in this situation. This ensures that a console is displayed, even if it is slow. Signed-off-by: Simon Glass <sjg@chromium.org>
