From: Li Zhang <zhlcindy(a)linux.vnet.ibm.com>
To support VFIO for PPC, it is needed spapr-vfio-pci-host-bridge in
QEMU. This patch is to add one capability for it.

Having no access to the appropriate hardware, I can't verify if this is
the correct name for the device or not, but will assume it is.
ACK for what you have, but this only detects the capability and exposes
it to the commandline generator - it's better to not push something that
changes the ABI (the list of capabilities are included when
saving/migrating) without also having a patch that demonstrates its
utility (and that patch should also add a test case to qemuxml2argvtest)
