[PATCH v2] docs: submitting-patches: Advertise b4

[Mark Brown <broonie@kernel.org>]

b4 is now widely used and is quite helpful for a lot of the things that
submitting-patches covers, let's advertise it to submitters to try to make
their lives easier and reduce the number of procedural issues maintainers
see.
