This needs to be done everywhere in order for us to drive any display! As such as soon as we tested on a non-CougarPoint chipset, we failed to bring up any DisplayPorts and generated a nice set of assertion failures in the process. At least one part of our logic is working, the part that assumes that we have no idea what we are doing.
