dt-bindings: iio: adc: sd-modulator: fix io-channel-cells

Browse Source 
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.

Fixes: af11143757 ("IIO: Add DT bindings for sigma delta adc modulator")

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.
- #io-channel-cells = <1>: See the IIO bindings section "IIO consumers".
- #io-channel-cells = <0>: See the IIO bindings section "IIO consumers".
Example node:
ads1202: adc@0 {
compatible = "sd-modulator";
#io-channel-cells = <1>;
#io-channel-cells = <0>;
};
