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.
