[PATCH v2 00/16] powernv: introduce pnv-phb base/proxy devices

[Daniel Henrique Barboza]

Hi,

This v2 is considerable different from the first version due to the
review provided by Mark Cave-Ayland.

We're now preserving all PnvPHB3/4/5 implementations already in place.
The PnvPHB device now acts as a base/proxy of the existing PHBs, which
are turned into backends of the base PnvPHB device.

QOM is being more used this time by passing through properties to the
PHB backends from the base device, and by setting the phb->version
via global machine properties in each machine.

The changes made impact both user creatable and default devices, meaning
that now the powernv machines are using the PnvPHB base device in all
circunstances.

The one thing that I didn't change from v1 is the root port revamp. I
didn't find enough reason to do the same thing we did with the PnvPHBs,
given that all that differs them is the reset() callback of
phb4_root_port. This means that patches 14-17 from v1 are still mostly
the same.


Changes from v1:
- lots of changes in patches 1-6 and 7 due to the change of direction
- patch 10 from v1: removed
- PnvPHB.version is now being removed in patch 16
- several other minor changes due to changes in the initial patches
