You call this mii_pins, but include mdio pins in there as well. Can you
separate them out? Then some board which uses rmii can simply reuse the
entry.

This is SoC specific pin list. Such board specific pins should not make
it here.

I doubt this is required. This property is to pass a handle to the phy,
not mdio bus.
