hv: Remove need for init_fallback_iommu_domain and fallback_iommu_domain

Browse Source 
In the presence of SOS, ACRN uses fallback_iommu_domain which is the same
used by SOS, to assign domain to devices during ACRN init. Also it uses
fallback_iommu_domain when DM requests ACRN to remove device from UOS domain.
This patch changes the design of assign/remove_iommu_device to avoid the
concept of fallback_iommu_domain and its setup. This way ACRN can commonly
treat pre-launched VMs bringup w.r.t. IOMMU domain creation.
