crypto: arm64/sm4 - add CE implementation for CTS-CBC mode
This patch is a CE-optimized assembly implementation for CTS-CBC mode.
Benchmark on T-Head Yitian-710 2.75 GHz, the data comes from the 218 mode of
tcrypt, and compared the performance before and after this patch (the driver
used before this patch is cts(cbc-sm4-ce)). The abscissas are blocks of
different lengths. The data is tabulated and the unit is Mb/s:
Before:
cts(cbc-sm4-ce) | 16 64 128 256 1024 1420 4096
----------------+--------------------------------------------------------------
CTS-CBC enc | 286.09 297.17 457.97 627.75 868.58 900.80 957.69
CTS-CBC dec | 286.67 285.63 538.35 947.08 2241.03 2577.32 3391.14
After:
