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.
