So going through the list I don't believe this is correct.

Inserting bus-type into the PHY layer is borrowing from one domain 
linux-media and pushing the concept into PHYs.

phy-cells = 1 with CPHY/DPHY specified in the consumer, as was Rob's 
suggestion will specify the mode.

Then to understand if we are in regular or combo mode, we parse the 
ports/endspoints in the PHY node as we've agreed already.
