[PATCH] UBUNTU: kvm: [config] Enable VFIO

[Julio Montes]

BugLink: https://bugs.launchpad.net/ubuntu/+source/linux-kvm/+bug/1759421

Kata containers support VFIO devices, these devices
can be hot added to running containers

Next configs are needed to support VFIO
* CONFIG_DMAR_TABLE
* CONFIG_HAVE_INTEL_TXT
* CONFIG_INTEL_IOMMU
* CONFIG_INTEL_IOMMU_DEFAULT_ON
* CONFIG_INTEL_IOMMU_FLOPPY_WA
* CONFIG_INTEL_IOMMU_SVM
* CONFIG_IOMMU_API
* CONFIG_IOMMU_IOVA
* CONFIG_IOMMU_SUPPORT
* CONFIG_IRQ_REMAP
* CONFIG_PCI_ATS
* CONFIG_PCI_PASID
* CONFIG_VFIO
* CONFIG_VFIO_IOMMU_TYPE1
* CONFIG_VFIO_PCI
* CONFIG_VFIO_PCI_INTX
* CONFIG_VFIO_PCI_MMAP
* CONFIG_VFIO_VIRQFD
