ACPI: video: Use native backlight on Dell Inspiron N4010

Browse Source 
[ Upstream commit 03c440a26c ]

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.
