The made conversion changes are not exactly the ones, which were asked to
be done.

Commit 34af4554fb0c ("of: Introduce for_each_*_child_of_node_scoped()
to automate of_node_put() handling") says it clearly:

    Note that, in the vast majority of cases, the _available_ form should be
    used and as code is converted to these scoped handers, we should confirm
    that any cases that do not check for available have a good reason not
    to.

So, likely this and many other similar changes miss information in their
commit messages, why for_each_available_child_of_node_scoped() form is
inapplicable, thus it still could be improved.
