crypto: aspeed - Use memcpy_from_sglist() in aspeed_ahash_dma_prepare()

Replace scatterwalk_map_and_copy() with memcpy_from_sglist() in
aspeed_ahash_dma_prepare(). The latter provides a simpler interface
without requiring a direction parameter, making the code easier to
read and less error-prone.

No functional change intended.
