MAINTAINERS: Add missing boards and config entries

As part of my usual round of build testing, output about missing
MAINTAINERS information was not logged, and thus often overlooked.
Correct that mistake by ensuring that I log the output of
genboardscfg.py every time. As part of that, address a number of
missing MAINTAINERS entires. In the case of a missing file, I have put
the original submitter down. In the rest of the cases I have added the
config (and sometimes relevant header file) to the existing set of file
globs.
