A few drivers which need a work-queue must cancel work at driver detach.
Some of those implement remove() solely for this purpose. Help drivers to
avoid unnecessary remove and error-branch implementation by adding managed
verision of work initialization. This will also help drivers to avoid
mixing manual and devm based unwinding when other resources are handled by
devm.

The kerneldoc for devm_delayed_work_autocancel() contains invalid
parameter description.
Fix the parameter description. And while at it - make it more obvous that
this function operates on delayed_work. That helps differentiating with
resource-managed INIT_WORK description (which should follow in near future)
Fixes: 0341ce5443 ("workqueue: Add resource managed version of delayed work init")
