ACPI / video: Add quirk to force acpi-video backlight on Samsung 670Z5E

BugLink: http://bugs.launchpad.net/bugs/1768429

commit bbf03861 upstream.

Just like many other Samsung models, the 670Z5E needs to use the acpi-video
backlight interface rather then the native one for backlight control to
work, add a quirk for this.
