Subject[net-next PATCH v5 12/15] net/fsl: Use fwnode_mdiobus_register()
Date
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.

Changes in v5: None
Changes in v4:
- Cleanup xgmac_mdio_probe()

Changes in v3:
- Avoid unnecessary line removal
- Remove unused inclusion of acpi.h

Changes in v2: None
