For assigned SVA capable devices, needs to bind guest pasid table
to host. Intel vIOMMU emulator captures device selective context
cache flush, and propagate the guest pasid table pointer to host,
in host iommu driver configs the guest pasid table pointer in its

This patch adds IOMMUSVAContext as an abstract for virt-SVA in
Qemu.
IOMMUSVAContext is per-PASID(Process Address Space Identity).

devices would use IOMMUSVAConte

This patch shows the idea of how a device is binded to a PASID tagged
AddressSpace.
when Intel vIOMMU emulator detected a pasid table entry programming
from guest. Intel vIOMMU emulator firstly finds a VTDPASIDAddressSpace
with the pasid field of pasid cache invalidate request.
* If it is to bind
VFIO is the bridge for vIOMMU and host IOMMU. Needs to provide API
for vIOMMU emulator to set configs to host IOMMU. In this patchset,
such API is exposed in hw/pci.

This patch records assigned devices in a list within Intel vIOMMU
emulator. The recorded info can be used to filter out affect assigned
devices when Qemu captured guest's cache invalidate request.

IOMMU notifiers before are mostly used for [dev-]IOTLB stuffs. It is not
