Subject: [PATCH] dt-bindings:iio:adc:st,spear600-adc: txt to yaml format conversion.

Straight forward conversion from spear-adc.txt into yaml format.

Signed-off-by: Rodrigo Gobbi <rodrigo.gobbi.7@...il.com>

After the conversion to yaml file, I was not sure about the
maintainers yaml field. It looks like the original driver author,
Stefan Roese, is not active contributing.
@Jonathan, I was not sure about it and I've added you on that field
as I've noticed at other yaml`s, but feel free to give any suggestions on that
or how to proceed in this case.

Also noticed that the driver was moved out of staging, but the .txt was not
in that time. Added the yaml in the proper path (out of staging as the driver).
Tks and best regards.
