The presenters for xive on P9 and P10 are mostly similar but the
behavior can be tuned through a few CQ registers. This patch adds a
"get_config" method, which will allow to access that config from the
presenter in a later patch.
For now, just define the config for the TIMA version.

yes. That's how I caugh it.
QEMU has an avocado test :
build/tests/venv/bin/avocado -t machine:pseries build/tests/avocado/boot_linux.py
which hangs. More tests would be good to have.

config registers and modifications to the CQ unit are spanned to the
others.
