Iommu_group_create_direct_mappings

WebUpdate the iommu_map() API to pass in the GFP argument, and fix all call sites. Replace iommu_map_atomic(). Audit the "enterprise" iommu drivers to make sure they do the right thing. Intel and S390 ignore the GFP argument and always use GFP_ATOMIC. This is problematic for iommufd anyhow, so fix it. AMD and ARM SMMUv2/3 are already correct.
