[PATCH v2 1/3] checkpatch: Make Helped-by tag supported

[Dragan Simic <dsimic@manjaro.org>]

Providing a Helped-by tag fits well to indicate someone had helped with the
development of a patch, to the level that still doesn't warrant providing
a Co-developed-by tag, but is much more than it would've been indicated by
providing a Suggested-by tag.  The Helped-by tag been already used recently
a few times in accepted patches. [1]

With all this in mind, let's have Helped-by supported in checkpatch.pl.
