    realtek: mdio: rename main mdio bus
    
    Looking at the Realtek mdio busses there are curently the following
    
    root at OpenWrt:~# mdio
    1b000000.switchcore:mdio-controller-mii
    fixed-0
    realtek-aux-mdio
    realtek-serdes-mdio
    rtldsa_mdio-0
    
    The main mdio bus for the phys is named after the dts node it belongs
    to (1b000000.switchcore:mdio-controller-mii). As it is attached to the
    controller node it is even more confusing.
    
    Align the naming to the other busses and use "realtek-mdio".
