Merge branch 'mctp-kunit-tests'

Jeremy Kerr says:

====================
MCTP kunit tests

This change adds some initial kunit tests for the MCTP core. We'll
expand the coverage in a future series, and augment with a few
selftests, but this establishes a baseline set of tests for now.

Thanks to the kunit folks for the framework!
