ACRN cleans up the IOMMU domain and other data structures that represents the state of device assigment to POST_LAUNCHED_VM. This is with the help of hypercalls from SOS DM. Under scenarios where DM execution can get terminated abruptly or due to bugs in DM, hypercalls responsible for cleaning up ACRN cannot happen. This leaves ACRN device representation/resource assignment in an incorrect state. This patch cleans up the IOMMU resource and other data structures upon shutdown of POST_LAUNCHED_VM.
