One entry that should be in the generic docs rather than here.

Given the documentation generation scripts don't support multiple
entries for a given attribute name an that one is 'standard'
we should just add it to the main file as otherwise the chances
are very high of accidentally getting duplication when it
turns up in another driver ABI doc.

We may need to move some of the others later if they turn out
to occur in multiple drivers but they are obscure enough to
be fine in this file for now.

Thanks,

Jonathan

This particular one is normal ABI, so should just be added to the list
in sysfs-bus-iio alongside all the other calibscale entries.
