When building sandbox_defconfig with CONFIG_DM_VIDEO=n a link time error occurs:

in function `sandbox_serial_pending': drivers/serial/sandbox.c:101: undefined reference to `video_sync_all'

video_sync_all() is only defined if we have CONFIG_DM_VIDEO=y.

Calling this function in a serial driver looks quite hackish but at least let's add the missing build constraint.
