MAINTAINERS: comment out invalid maintainers

The "S:    Orphan" in MAINTAINERS means that the maintainer in the
"M:" field is unreachable (i.e. the email address is not working).
(Refer to the definition of "Orphan" adopted in U-Boot
in the log of commit 31f1b654b2f395b69faa5d0d3c1eb0803923bd3b,
"boards.cfg: move boards with invalid emails to Orphan")

For patch files adding global changes, scripts/get_maintainer.pl
adds bunch of such invalid email addresses, which results in
tons of annoying bounce emails.

This commit can be reproduced by the following command:

find . -name MAINTAINERS | xargs sed -i -e '
/^M:[[:blank:]]/ {
      N
      /S:[[:blank:]]Orphan/s/^/#/
}
'
