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.
