ACPI: video: Use native backlight on Acer Aspire 5783z

Browse Source 
The Acer Aspire 5783z shipped with Windows 7 and as such does not trigger
our "win8 ready" heuristic for prefering the native backlight interface.

Still ACPI backlight control doesn't work on this model, where as the
native (intel_video) backlight interface does work. Add a quirk to
force using native backlight control on this model.
