[Intel-gfx] [PATCH 1/4] Revert "drm/i915: Use a dmi quirk to skip a broken SDVO TV output."

[Zhenyu Wang]

This reverts commit 6070a4a928f8c92b9fae7d6717ebbb05f425d6b2.

The quirk for this SDVO device on specific board will break same
device on another OEM's output config. Instead multifunction SDVO
support would fix this.
