Zide Chen 5f87e716b8 hv: release IOMMU irte when releasing ptirq remapping entries ...

IRTE is freed if ptirq entry is released from remove_msix_remapping() or
remove_intx_remapping(). But if it's called from ptdev_release_all_entries(),
e.g. SOS shutdown/reboot, IRTE is not freed.

This patch adds a release_cb() callback function to do any architectural
specific cleanup. In x86, it's used to release IRTE.

On VM shutdown, vpci_cleanup() needs to remove MSI/MSI-X remapping on
ptirq entries, thus it should be called before ptdev_release_all_entries().
