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.
