    kernel: net: phy: realtek: fix rtl822x_probe on unsupported devices
    
    Calling rtl822x_probe() on phy devices which uses the rtl822x_read_mmd()
    and rtl822x_write_mmd() functions makes no sense and the probe ends with
    an EOPNOTSUPP error.

    (cherry picked from commit 5af7d47cd7fb936dc7d640e1ba63443152d0416a)
