Until now this driver only exposed the raw value of the channels. With
this patch, the scale value is also exposed.
It depends of a regulator supply, and unlike most of the other driver, do
not having this regulator won't prevent to use the driver. The reason for
it is to allow to continue to use this driver with an old device tree. If
there is no regulator supply then the scale won't be exposed.

The equivalent of both of these are now done via macro magic when
the relevant register calls are made. The actual structure
elements will shortly go away.

There are a few more little cleanups that could be done on this driver, but
I don't think any are sufficient to justify not moving it out of staging.
It's a very simple driver (presumably for a simple part) so not much that can
go wrong. I think it was only ever in staging because that's where IIO was
as a whole at the time and then we forgot about it!
