This is a preparation for the next commit adding support for register read and write functions on AD7606. Since sometimes a bus will be used, it has been agreed during ad3552's driver implementation that the device's driver bus is the backend, whose device node will be a child node. To provide the special callbacks for setting the register, axi-adc needs to pass them to the child device's driver through platform data.
