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.
Fixes: 47dd7a540b8a ("net: add support for STMicroelectronics Ethernet controllers.")
