@ribdp - Do these changes look good for a merge?

[ribdp]

So the documentation would need some updates -

1. We need to add the device name here and then run that script https://github.com/analogdevicesinc/PrecisionToolbox/blob/main/docs/source/reference_api/gen_sysobj_doc.m#L36
2. Index.rst and ad4170_iio.rst would then get updated/generated, and would need to be added to the PR
3. The existing CI/gen_doc changes can be removed as they aren't relevant to the new documentation system

@ribdp - I've made the changes with the documentation- does it look ok now?

[ribdp]

Just one final change from my end - the device needs to be mentioned here as well - https://github.com/analogdevicesinc/PrecisionToolbox/blob/main/docs/source/index.rst

LGTM otherwise
