I think we can do slightly better here. The only caller of
acpi_is_video_device() is in drivers/acpi/video_detect.c so we can move
it there and make it static (is_video_device()).

Then we can name this one acpi_is_video_device() instead and in addition
make it take struct acpi_device as parameter instead of acpi_handle (I
think we should not use acpi_handles in drivers if possible).
