vfio: platform: support No-IOMMU mode
The vfio No-IOMMU mode was supported by this 'commit 03a76b60f8ba2797 ("vfio: Include No-IOMMU mode")', but it only support vfio-pci. Using vfio_iommu_group_get/put, but not iommu_group_get/put, the platform devices can be exposed to userspace with CONFIG_VFIO_NOIOMMU and the "enable_unsafe_noiommu_mode" option enabled. From 'commit 03a76b60f8ba2797 ("vfio: Include No-IOMMU mode")', "This should make it very clear that this mode is not safe. Additionally, CAP_SYS_RAWIO privileges are necessary to work with groups and containers using this mode. Groups making use of this support are named /dev/vfio/noiommu-$GROUP and can only make use of the special VFIO_NOIOMMU_IOMMU for the container. Use of this mode, specifically binding a device without a native IOMMU group to a VFIO bus driver will taint the kernel and should therefore not be considered supported."
