net: usb: smsc95xx: fix external PHY reset
An external PHY needs settling time after power up or reset. In the bind() function an mdio bus is registered. If at this point the external PHY is still initialising, no valid PHY ID will be read and on phy_find_first() the bind() function will fail. If an external PHY is present, wait the maximum time specified in 802.3 45.2.7.1.1.
