video: annotate switch/case fall-through

The generic DM video code uses an implicit switch/case fallthrough to
provide fallback code paths when certain colour depths are not enabled.

Add our "fallthrough;" statement-like macro to the video_fill() function
to avoid a warning when GCC's -Wimplicit-fallthrough warning option is
enabled.
