In pre-launched VM the GPA of vmsix BAR which is used for vmsix over msi is calculated/allocated by acrn-config tool. The GPA needs to be assigned to vdev when vdev is initialized. The assignment is only needed for pre-launched VM. For SOS kernel will reprogram the Bar base when startup. For post-launched VM the Bar GPA will be assigned by device model via hypercall.
