The ChaCha20-Poly1305 library code uses the sg_miter API to process input presented via scatterlists, except for the special case where the digest buffer is not covered entirely by the same scatterlist entry as the last byte of input. In that case, it uses scatterwalk_map_and_copy() to access the memory in the input scatterlist where the digest is stored. This results in a dependency on crypto/scatterwalk.c and therefore on CONFIG_CRYPTO_ALGAPI, which is unnecessary, as the sg_miter API already provides this functionality via sg_copy_to_buffer(). So use that instead, and drop the dependencies on CONFIG_CRYPTO_ALGAPI and CONFIG_CRYPTO.
