Andrew Halaney 23ee06762c net: stmmac: Handle disabled MDIO busses from devicetree
[ Upstream commit e23c0d21ce9234fbc31ece35663ababbb83f9347 ]

Many hardware configurations have the MDIO bus disabled, and are instead
using some other MDIO bus to talk to the MAC's phy.

of_mdiobus_register() returns -ENODEV in this case. Let's handle it
gracefully instead of failing to probe the MAC.
