Hi Russell

What do you think about my proposal to solve it? Only instantiate
phylink for CPU and DSA ports if there is a fixed-link or phy-handle
in DT?

I also looked at the code before this integration. I had the open
question of if it was possible to just have a phy-mode property,
without fixed link. And the answer is no.

So i will formally propose my solution.
