vfio: Provide module option to disable vfio_iommu_type1 hugepage support
Add a module option to vfio_iommu_type1 to disable IOMMU hugepage
support. This causes iommu_map to only be called with single page
mappings, disabling the IOMMU driver's ability to use hugepages.
This option can be enabled by loading vfio_iommu_type1 with
disable_hugepages=1 or dynamically through sysfs. If enabled
dynamically, only new mappings are restricted.
