While developing this driver, we glossed over AD7389-4 since we didn't
have hardware to test it. However, it should be trivial enough to add
support without testing. It is basically the same as AD7380-4 but
instead of no internal reference, it has no external reference. And we
already have support for chips with internal reference only (ADAQ).

We have the typical DT bindings/driver/documentation patches for it plus
a few patches to shuffle around the existing code for supporting chips
with internal-reference-only to make it generic enough to support this
chip as well.
