[PATCH] video: output: remove video_output_{register,unregister}

[Pavel Roskin <proski@gnu.org>]

Signed-off-by: Pavel Roskin <proski@gnu.org>

video_output_register() and video_output_unregister() are not called
anywhere in the kernel code.  Also remove the fallback implementation
from the header.
