iommu: Add iommu_copy_struct_from_user_array helper
Wrap up the data pointer/num sanity and __iommu_copy_struct_from_user()
call for iommu drivers to copy driver specific data at a specific location
in the struct iommu_user_data_array.
And expect it to be used in cache_invalidate_user ops for example.
