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

This reverts commit 6070a4a928f8c92b9fae7d6717ebbb05f425d6b2.

The quirk for this SDVO device on IBM specific board is just a hack
in old code which showed the broken multifunction SDVO support in
the driver. Multifunction SDVO patch provided the right fix for it.
