I think we need to understand this better. Why does it fail?
I gave a test on an imx6q-sabresd and the Ethernet PHY (AR8031) could be properly detected using reset-{assert-us,deassert-us,gpios} properties inside the mdio node.
Is this a Micrel KSZ8081 specific issue?
Please report this issue to the Ethernet PHY folks.
