[net-next PATCH v2 09/14] net/fsl: Use fwnode_mdiobus_register()

[Calvin Johnson <calvin.johnson@xxxxxxxxxxx>]

fwnode_mdiobus_register() internally takes care of both DT
and ACPI cases to register mdiobus. Replace existing
of_mdiobus_register() with fwnode_mdiobus_register().

Note: For both ACPI and DT cases, endianness of MDIO controller
need to be specified using "little-endian" property.
