drm/i915: Stop trying to use ACPI lid status to determine LVDS connection.
I've been getting more and more quirk reports about this. It seems clear at this point that other OSes are not using this for determining whether the integrated panel should be turned on, and it is not reliable for doing so. Better to light up an unintended panel than to not light up the only usable output on the system. Signed-off-by: Eric Anholt <eric@anholt.net> Acked-by: Jesse Barnes <jbarnes@virtuousgeek.org>
