Hans de Goede 23d28cc044 ACPI: video: Add backlight=native DMI quirk for Dell Studio 1569 ...

The Dell Studio 1569 predates Windows 8, so it defaults to using
acpi_video# for backlight control, but this is non functional on
this model.

Add a DMI quirk to use the native intel_backlight interface which
does work properly.
