Hmmm ...  In the MPC8572E and P1022DS manuals I don't see the terminology
group used for message registers.  The MPIC global timers on the other hand
do use group A and group B.  I will definitely add the 'mpic-' prefix, but
unless I am looking in the wrong place in the manuals, then I am not so
sure there are MPIC message register groups.  As a side note,
the term "register block" pops up in a few places not related to
message registers.

If you feel like group is a more idiomatic term, I can change it.
