>Once we've determined that the sink is MST capable we never end up
>running through the full detect cycle again, despite getting HPDs.
>Fix tht by ripping out the incorrect piece of code responsible.
>
>This got broken when I moved the long HPD handling to the ->detect()
>hook, but failed to remove the leftover code.
