Hi,

This is a rebase on top of ppc-7.2 of the previous patches sent
here:

https://lists.gnu.org/archive/html/qemu-devel/2022-07/msg01542.html

Now that we have the pnv-phb rework in the tree.

As a recap, the changes introduced in this series compared to what we've
done in "[PATCH v2 00/16] powernv: introduce pnv-phb base/proxy
devices" [1], is:

- the Root Buses objects are now inheriting phb-id and chip-id. This
turned out to be a clean way of keeping the code QOM compliant, without
having to do things like dev->parent_bus->parent. All the attributes
that the root port needs are found in its bus parent;

- the logic exclusive to user created devices is all centered in a
single helper inside pnv-phb realize(). PHB3/PHB4 realize() are
oblivious to whether the device is user created or not. I believe this
approach is clearer than what I was doing before.
