Oh, sorry, I meant we use both MACs on Zynq, however the PHYs are on the MDIO
bus of the first MAC. So, the second MAC is used for ethernet but not for MDIO,
and so it does not have any PHYs under its DT node. It would be nice if there
were a way to tell macb not to bother with MDIO for the second MAC, since that's
handled by the first MAC.

I guess a good longer-term solution to all these problems would be to treat the
MAC and MDIO as seperate devices, like davinci seems to be doing.
