Subject: [PATCH 08/15] dt-bindings: iio: adc: adi,ad4030: Add 4-lane per channel bus width option

AD4630 has two input channels and each of them can have it's data output in
4 dedicated lines, resulting in a total of 8 data lines used by the device.
Document the option that specifies the case where AD4630 and similar ADCs
provide data through 8 SPI lines.
