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.
