Hmm. Based on the history there seems to be some kind of
screwup in the combo PHY code wrt. ports that are not
actually present in the SKU. The spec says we should rely
on hpd to figure out what ports are actually present. So
looks like the combo PHY code needs quite a bit of redesign :(
I guess I'll leave this out until then.
