Add some KUnit tests for the IIO GTS helpers.

These tests were originally part of the BU27034 ALS sensor driver series.
https://lore.kernel.org/all/cover.1679915278.git.mazziesaccount@gmail.com/

Merging the tests was postponed because we lacked of a good generic way
of creating tests devices for testing the devm managed interfaces. Now we
have kunit_device APIs being merged (seems like they'll be part of the
v6.8-rc1) so precondition for merging these tests are (being) met.

The series is based on
commit ab27740f7665 ("Merge tag 'linux_kselftest-next-6.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest")
in Linus' tree.

I can rebase and resend when v6.8-rc1 is out if needed.

Please ignore the patch 1/3 above. It has been already merged. 
Unfortunately I noticed this commit being in the series only after 
sending the cover-letter. In order to not consumer reviewer's time, I 
omitted sending the 1/3 - so it's missing the series on purpose. 
Subsequent versions won't include this patch anymore.

Also, this file is not changed by patches 2/3 and 3/3.

Sorry!
