    realtek: Switch ApresiaLightGS120GT-SS RTL8231 driver
    
    Switch the implementation for the RTL8231 GPIO expander to the new
    driver.
    
    This allows specifying the GPIO driving the RTL8231's reset as a proper
    MDIO reset line, so the gpio-hog can be dropped. Since it was pinned at
    a high level, the reset line is actually active-low (i.e. high when not
    in reset).
