ACPI / video: Add some Samsung models to disable_native_backlight list

commit 7d0b93499f4879ddbc75d594f4ea216ba964f78e upstream.

Several Samsung laptop models (SAMSUNG 870Z5E/880Z5E/680Z5E and
SAMSUNG 370R4E/370R4V/370R5E/3570RE/370R5V) do not have a working
native backlight control interface so restore their acpi_videoX
interface.
