crypto: riscv - add vector crypto accelerated SM4

Browse source

Add an implementation of SM4 using the Zvksed extension.  The assembly
code is derived from OpenSSL code (openssl/openssl#21923) that was
dual-licensed so that it could be reused in the kernel.  Nevertheless,
the assembly has been significantly reworked for integration with the
kernel, for example by using a regular .S file instead of the so-called
perlasm, using the assembler instead of bare '.inst', and greatly
reducing code duplication.
