drm/i915: Use a dmi quirk to skip a broken SDVO TV output.

commit 6070a4a928f8c92b9fae7d6717ebbb05f425d6b2 upstream.

This IBM system has a multi-function SDVO card that reports both VGA
and TV, but the system has no TV connector.  The TV connector always
reported as connected, which would lead to poor modesetting choices.
