ACPI: video: Add backlight=native DMI quirk for Lenovo Ideapad Z470
[ Upstream commit 96b709be183c56293933ef45b8b75f8af268c6de ]
The Lenovo Ideapad Z470 predates Windows 8, so it defaults to using
acpi_video for backlight control. But this is not functional on this
model.
Add a DMI quirk to use the native backlight interface which works.
