    hw/ppc/e500: Add missing device tree properties to i2c controller node

    When compiling a decompiled device tree blob created with dumpdtb, dtc complains
    with:

      /soc@e0000000/i2c@3000: incorrect #address-cells for I2C bus
      /soc@e0000000/i2c@3000: incorrect #size-cells for I2C bus

    Fix this by adding the missing device tree properties.
