ad7380-4 is the only device from ad738x family that doesn't have an internal reference. Moreover it's external reference is called REFIN in the datasheet while all other use REFIO as an optional external reference. Update documentation to highlight this.

2024-08-03docs: iio: ad7380: add support for single-ended partsJulien Stephan1-0/+42
The AD7380 family has some compatible single-ended chips: AD7386/7/8(-4). These single-ended chips have a 2:1 multiplexer in front of each ADC. They also include additional configuration registers that allow for either manual selection or automatic switching (sequencer mode), of the multiplexer inputs. Add a section to describe this.
