address change

Oops, I forgot to update the MAINTAINERS file a couple of months ago,
when the address there stopped working.

Honestly, I haven't really had much involvement with the frv, mn10300
or sh ports for almost 15 years, so I wouldn't mind if someone else
stepped up and took over, but until someone does, I don't mind
reviewing the occasional patch, so it's best if it can reach me ;-)
