As everything else is now handled by devm managed releases the
triggered buffer setup and IIO device registration can also be
moved over to their devm forms allowing dropping of remove().

I wonder if it's obvious to everyone that removing this call as a consequence
of not needing  .remove() is clear enough that it does not deserve a mention
in the commit message?

Note that I don't find it particular important so I will still ack it and leave it
up to you :)
