A few headers was useless: remove them, and also sort them in alphabetic
order.

Hmm. Given the headers in question are mostly only useless (I think)
in the sense they are always included by something else, I'm
not sure this patch is worth the churn.

It's also tricky to see which ones were actually removed
given the combination with sorting.
I think it's just kernel.h, device.h, err.h all of which
are used in various ways and often directly included.

The other one is the iio/sysfs.h file.  That one we could
do to eventually kill off entirely, so happy to see that
one alone go.

Actually, as I needed to add a header, I wanted to sort the list to put
it in the right place and then some of the header looked superfluous
that why I remove some of them. For example there was no reason to use
slab.h or of.h.

I am nit sure to know what do you want with this patch.

Agreed on those two. I missed them probably because of the re organization
being combined with them.  No specific allocations except
via interfaces from elsewhere and no direct use of the devicetree
stuff, so fine to drop them.

Break it in two.  Drop the unwanted ones first, then reorganize.
That way the diff is easy to read.  Clearly I missed some
changes on my first read as it stands!
