Jason Gunthorpe 4f2e59ccb6 iommu: Add iommu_copy_struct_from_full_user_array helper
The iommu_copy_struct_from_user_array helper can be used to copy a single
entry from a user array which might not be efficient if the array is big.

Add a new iommu_copy_struct_from_full_user_array to copy the entire user
array at once. Update the existing iommu_copy_struct_from_user_array kdoc
accordingly.
