The change from v1 is that I have altered the MMIO size check to fail
the emulation in case the size exceeds 8 bytes. That brought some
cleanups and another fix along with it, we were returning to userspace
in case of failure instead of the guest.

This has now become an MMIO series, but since the first commit has
been reviewed already, I'm leaving it here.

v1:
