I don't see a dependency on TI_DAVINCI_MDIO in the code. All you need
is an MDIO bus so that your phy-handle has somewhere to point. But that
could be a GPIO bit banger.

What i do think is missing here is a dependency on PHYLIB.

If possible, it would be good to also have it compile when
COMPILE_TEST is set.
