MAINTAINERS: Remove Mark Gross from relevant entries

Sending mail to Mark's Intel address results in the Intel mail server
rejecting the mail. Dave Hansen confirmed he left Intel.  The kernel.org
address seems to work, but there was no reply from Mark on the discussion
about broken email settings and his maintainer entries.

So drop him from all maintainer entries and move him to credits.
