io-channel-cells should be <0> since sigma delta modulator exports only
one channel, as described in ../iio/iio-bindings.txt "IIO providers"
section. Only the phandle is necessary for IIO consumers in this case.

 Required properties:
 - compatible: should be "ads1201", "sd-modulator". "sd-modulator" can be use
        as a generic SD modulator if modulator not specified in compatible list.
