    realtek: switch RTL8231 driver for D-Link DGS-1210
    
    Update the common external GPIO DTSI file for the DGS-1210 devices to
    use an MDIO device on the auxilairy MDIO bus, as the original driver was
    doing behind the screen.
    
    Switching to the new driver will allow for full pin-control and will no
    longer reset pin config set by the bootloader.
