ACPI / video: Add use native backlight quirk for the ThinkPad W530
Like all of the other *30 ThinkPad models, the W530 has a broken acpi-video backlight control. Note in order for this to actually fix things on the ThinkPad W530 the commit titled: "nouveau: Don't check acpi_video_backlight_support() before registering backlight" is also needed.
