crypto: sm4 - export sm4 constant arrays
Export the constant arrays fk, ck, sbox of the SM4 algorithm, and add the 'crypto_sm4_' prefix, where sbox is used in the SM4 NEON implementation for the tbl/tbx instruction to replace the S-BOX, and the fk, ck arrays are used in the SM4 CE implementation. Use the sm4ekey instruction to speed up key expansion operations. Signed-off-by: Tianjia Zhang <tianjia.zhang@linux.alibaba.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
