Subject: [net-next PATCH v7 12/16] net: mdiobus: Introduce fwnode_mdiobus_register()

Introduce fwnode_mdiobus_register() to register PHYs on the  mdiobus.
If the fwnode is DT node, then call of_mdiobus_register().
If it is an ACPI node, then call acpi_mdiobus_register().

Signed-off-by: Calvin Johnson <calvin.johnson@....nxp.com>
---

Changes in v7:
- Move fwnode_mdiobus_register() to fwnode_mdio.c

Changes in v6: None
Changes in v5: None
Changes in v4:
- Remove redundant else from fwnode_mdiobus_register()

Changes in v3:
- Use acpi_mdiobus_register()

Changes in v2: None
