[RFC PATCH net-next v2 06/11] net: mdio: of: wrap fwnode_mdio_parse_addr() in of_mdio_parse_addr()

["Clément Léger" <clement.leger@bootlin.com>]

Since function fwnode_mdio_parse_addr() returns the same value that is
done by of_mdio_parse_addr() and has the same behavior, wrap the first
one. The function was switched as non static in of_mdio.c to avoid
including fwnode_mdio.h in of_mdio.h.
