ACPI / video: Dummy acpi_video_register should return error code 



The inline acpi_video_register stub simply allows compilation on systems
with CONFIG_ACPI_VIDEO disabled. the dummy acpi_video_register does not
register an acpi_bus_driver at all. The inline acpi_video_register should
return to indicate lack of support when attempting to register an
acpi_bus_driver on such a system with CONFIG_ACPI_VIDEO disabled.
