MAINTAINERS: Don't list Andrzej Zaborowski for various components

Andrzej Zaborowski is listed as an "Odd Fixes" maintainer for the
nSeries, Palm and PXA2XX boards, as well as the "Maintained" status
Arm 32-bit TCG backend.

Andrzej's last email to qemu-devel was back in 2017, and the email
before that was all the way back in 2013.  We don't really need to
fill his email up with CCs on QEMU patches any more...

Remove Andrzej from the various boards sections (leaving them still
Odd Fixes with me as the backup patch reviewer).  Add Richard
Henderson as the maintainer for the Arm TCG backend, since removing
Andrzej would otherwise leave that section with no M: line at all.
