crypto: sm3,sm4 - move into crypto directory
The lib/crypto libraries live in lib because they are used by various drivers of the kernel. In contrast, the various helper functions in crypto are there because they're used exclusively by the crypto API. The SM3 and SM4 helper functions were erroniously moved into lib/crypto/ instead of crypto/, even though there are no in-kernel users outside of the crypto API of those functions. This commit moves them into crypto/. Cc: Herbert Xu <herbert@gondor.apana.org.au> Cc: Tianjia Zhang <tianjia.zhang@linux.alibaba.com> Cc: Eric Biggers <ebiggers@kernel.org> Signed-off-by: Jason A.
