NANO130: Fix OOM with packing algorithm at IAR linking

At IAR linking, the default method of 'initialize by copy' is 'auto', which will estimate
different packing algorithms, including complex 'lz77', for smallest memory footprint. But
the algorithm itself can consume some SRAM and cause OOM at linking time for NANO130, which
just has 16KiB SRAM. To avoid this error, always choose 'none' packing algorithm.
