ACPI / video: Add enable_native_backlight quirk for MacbookPro12,1
It seems that the latest generation of MacbookPro needs to use the native backlight driver, just like most modern laptops do, but it does not automatically get enabled as the Apple BIOS does not advertise Windows 8 compatibility. So add a quirk for this. Reported-by: Christopher Beland <beland@alum.mit.edu> Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
