spapr_drc: initial implementation of sPAPRDRConnector device
This device emulates a firmware abstraction used by pSeries guests to
manage hotplug/dynamic-reconfiguration of host-bridges, PCI devices,
memory, and CPUs. It is conceptually similar to an SHPC device,
complete with LED indicators to identify individual slots to physical
physical users and indicate when it is safe to remove a device. In
some cases it is also used to manage virtualized resources, such a
memory, CPUs, and physical-host bridges, which in the case of pSeries
guests are virtualized resources where the physical components are
managed by the host.
Guests communicate with these DR Connectors using RTAS calls,
generally by addressing the unique DRC index associated with a
particular connector for a particular resource. For introspection
purposes we expose this state initially as QOM properties, and
in subsequent patches will introduce the RTAS calls that make use of
it. This constitutes to the 'guest' interface.
On the QEMU side we provide an attach/detach interface to associate
or cleanup a DeviceState with a particular sPAPRDRConnector in
response to hotplug/unplug, respectively. This constitutes the
'physical' interface to the DR Connector.

spapr_pci_vfio: Add spapr-pci-vfio-host-bridge to support vfio
The patch adds a spapr-pci-vfio-host-bridge device type
which is a PCI Host Bridge with VFIO support. The new device
inherits from the spapr-pci-host-bridge device and adds an "iommu"
property which is an IOMMU id. This ID represents a minimal entity
for which IOMMU isolation can be guaranteed. In SPAPR architecture IOMMU
group is called a Partitionable Endpoint (PE).
Current implementation supports one IOMMU id per QEMU VFIO PHB. Since
SPAPR allows multiple PHB for no extra cost, this does not seem to
be a problem. This limitation may change in the future though.
Example of use:
Configure and Add 3 functions of a multifunctional device to QEMU:
(the NEC PCI USB card is used as an example here):
-device spapr-pci-vfio-host-bridge,id=USB,iommu=4,index=7 \
-device vfio-pci,host=4:0:1.0,addr=1.0,bus=USB,multifunction=true
-device vfio-pci,host=4:0:1.1,addr=1.1,bus=USB
-device vfio-pci,host=4:0:1.2,addr=1.2,bus=USB
where:
* index=7 is a QEMU PHB index (used as source for MMIO/MSI/IO windows
offset);
* iommu=4 is an IOMMU id which can be found in sysfs:
[aik@vpl2 ~]$ cd /sys/bus/pci/devices/0004:00:00.0/
[aik@vpl2 0004:00:00.0]$ ls -l iommu_group
lrwxrwxrwx 1 root root 0 Jun 5 12:49 iommu_group -> ../../../kernel/iommu_groups/4
