    realtek: fix dts warnings.
    
    Currently following warnings are given
    
    dts/rtl930x.dtsi:166.4-23: Warning (reg_format):
    /switchcore at 1b000000/i2c at 36c:reg: property has invalid length
    (8 bytes) (#address-cells == 2, #size-cells == 1)
    
    Obviously default address-cells size is fixed to 64 bit. Align
    with upstream and override address size to 32 bit.
