I/O port rework:
* Proposal by Hervé: move I/O port list registration to ISA
http://lists.gnu.org/archive/html/qemu-devel/2013-01/msg00508.html

This causes modeling issues since PCI VGA/QXL then register I/O ports
via ISADevice API (using NULL ISADevice* argument) and require an ISABus
in machines that may not have one (e.g., New World Macs).
(kind of a QOM multi-inheritence issue)

Trivial conversion patches were reviewed by me and merged already.
Remaining question is how to proceed conceptually and design-wise in
lack of memory and ISA maintainers.

Background is that ppc has no concept of PIO and needs a "forwarding"
from PCI I/O MemoryRegion to PIO currently:
