Zide Chen afdb938bc8 devices: vfio: prepare for vIOMMU support: multiple VFIO containers ... In preparation for virtio IOMMU support, implement global variables IOMMU_CONTAINERS and NO_IOMMU_CONTAINER to hold the VFIO containers for VFIO devices with or without IOMMu enabled respectively. Also implement vfio_get_container()help create VFIO container based on the more complicated policies. - all VFIO devices without attaching to virtio IOMMU devices share one VFIO container. - for IOMMU enabled devices, one VFIO container manages all devices under one VFIO group. - we don't support multiple IOMMU groups set to one VFIO container. Currently don't see an user case for this. BUG=b:181736020 TEST=unit tests.
