ACPI: video: Use native backlight on Dell Inspiron N4010
The Dell Inspiron N4010 does not have ACPI backlight control,
so acpi_video_get_backlight_type()'s heuristics return vendor as
the type to use.
But the vendor interface is broken, where as the native (intel_backlight)
works well, add a quirk to use native.
