keys, trusted: select hash algorithm for TPM2 chips
Added 'hash=' option for selecting the hash algorithm for add_key() syscall and documentation for it. Added entry for sm3-256 to the following tables in order to support TPM_ALG_SM3_256: * hash_algo_name * hash_digest_size Includes support for the following hash algorithms: * sha1 * sha256 * sha384 * sha512 * sm3-256 Signed-off-by: Jarkko Sakkinen <jarkko.sakkinen@linux.intel.com> Tested-by: Colin Ian King <colin.king@canonical.com> Reviewed-by: James Morris <james.l.morris@oracle.com> Reviewed-by: Mimi Zohar <zohar@linux.vnet.ibm.com> Acked-by: Peter Huewe <peterhuewe@gmx.de>
