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

commit bbf038618a24d72e2efc19146ef421bb1e1eda1a 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.
