[PATCH 00/10] enable pnv-phb user created devices

[Daniel Henrique Barboza <danielhb413@gmail.com>]

This series is built on top of

"[PATCH v3 00/12] powernv: introduce pnv-phb base/proxy devices" [1]

that is under review in [1]. I'm sending this last part of the pnv-phb
rework to allow everyone to see what's the endgame I'm planning with
this work.

The main differences between the approach taken here, versus the approach 
made by "[PATCH v2 00/16] powernv: introduce pnv-phb base/proxy
devices" [2], 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.

I'll respin/rebase this patches depending on the amount of changes
we have during the pnv-phb proxy device review.
