ACPI: video: Add backlight=native DMI quirk for Acer Aspire 3830TG 

[ Upstream commit 5e7a3bf65d ]

The Acer Aspire 3830TG predates Windows 8, so it defaults to using
acpi_video# for backlight control, but this is non functional on
this model.

Add a DMI quirk to use the native backlight interface which does
work properly.
