crypto: arm64/sm3 - add NEON assembly implementation
This patch adds the NEON acceleration implementation of the SM3 hash
algorithm. The main algorithm is based on SM3 NEON accelerated work of
the libgcrypt project.
Benchmark on T-Head Yitian-710 2.75 GHz, the data comes from the 326 mode
of tcrypt, and compares the performance data of sm3-generic and sm3-ce.
The abscissas are blocks of different lengths. The data is tabulated and
the unit is Mb/s:
