crypto: crypto4xx - replace crypto4xx_dev's scatter_buffer_size with constant
scatter_buffer_size is always set to PPC4XX_SD_BUFFER_SIZE. I don't think there's any point in keeping the variable around. Signed-off-by: Christian Lamparter <chunkeey@googlemail.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
