If the laptop doesn't actually have the port, it would be better to just add a connector table quirk to just remove it. However, the HDMI port may be on a docking station.

Fix by applying extented DDC probing for this connector.
Requires [PATCH] drm/radeon: Extended DDC Probing for Connectors with Improperly Wired DDC Lines
