SM3 generic library is stand-alone implementation, it is necessary
making the sm3-generic implementation to depends on SM3 library.
The functions crypto_sm3_*() provided by sm3_generic is no longer
exported.

Stand-alone implementation of the SM3 algorithm. It is designed
to have as little dependencies as possible. In other cases you
should generally use the hash APIs from include/crypto/hash.h.
Especially when hashing large amounts of data as those APIs may
be hw-accelerated. In the new SM3 stand-alone library,
sm3_transform() has also been optimized, instead of simply using
the code in sm3_generic.

Both crypto_sm3_update and crypto_sm3_finup have been
exported, exporting crypto_sm3_final, to avoid having to
use crypto_sm3_finup(desc, NULL, 0, dgst) to calculate
the hash in some cases.
