These types of cyclic calls do not exist anymore.
The fwnode_mdio does not call back into of_mdio but instead it directly
implements any necessary operations using the fwnode_handle.
The only calls happening are 'of_mdio -> fwnode_mdio' so that we
leverage the common fwnode handling and do not duplicate code.
