crypto: arm64/sm4 - add CE implementation for CCM mode
This patch is a CE-optimized assembly implementation for CCM mode.
Benchmark on T-Head Yitian-710 2.75 GHz, the data comes from the 223 and 225
modes of tcrypt, and compared the performance before and after this patch (the
driver used before this patch is ccm_base(ctr-sm4-ce,cbcmac-sm4-ce)).
The abscissas are blocks of different lengths. The data is tabulated and the
unit is Mb/s:
Before (rfc4309(ccm_base(ctr-sm4-ce,cbcmac-sm4-ce))):
