net: phy: realtek: Use generic genphy_parse_link() for RTL8211E
The problem with current implementation is that SPDDONE bit is 1 but link bit is zero. That's why phydev->link is setup to 0 which ending up in driver failure that link is not up. Log: Zynq> dhcp ethernet@e000b000 Waiting for PHY auto negotiation to complete....... done ethernet@e000b000: No link. There is at least 1ms delay between spddone bit and link up. Use genphy_read_status() instead of realtek implemenation which is working with page 11. Linux driver is also using generic implementation.
