amd_iommu: Send notification when invalidate interrupt entry cache
In order to support AMD IOMMU interrupt remapping emulation with PCI
pass-through devices, QEMU needs to notify VFIO when guest IOMMU driver
updates and invalidate the guest interrupt remapping table (IRT), and
communicate information so that the host IOMMU driver can update
the shadowed interrupt remapping table in the host IOMMU.
Therefore, send notification when guest IOMMU emulates the IRT
invalidation commands.
