This handles the exception code for the 74xx family, i.e. 7400, 7410,

This is another family that is quite well known, so it should be
straight-forward as well.

I'm not overly familiar with PPC exception handling detail, so I can't offer much in
the way of review I'm afraid. I could do a quick test and make sure nothing breaks
with my MacOS images though?
Also any thoughts on Christophe's question re: e300 PVRs at
https://lists.gnu.org/archive/html/qemu-ppc/2022-01/msg00592.html? I can handle
merging the OpenBIOS changes if someone can come up with a suitable fix.
ATB,
Mark.
