ACPI: video: Add backlight=native DMI quirk for Acer Aspire 4810T

[ Upstream commit 8ba5fc4c154aeb3b4620f05543cce426c62ed2de ]

The Acer Aspire 4810T 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.
