This was originally part of my vector crypto series, but was part
of a separate openssl merge request implementing GCM ghash as using
non-vector extensions.
As that pull-request
https://github.com/openssl/openssl/pull/20078
got merged recently into openssl, we could also check if this could
go into the kernel as well and provide a base for further accelerated
cryptographic support.
Changes in v4:
- rebase on top of riscv/for-next
- split out the scalar crypto implementation from the vector series
- refresh code from openSSL to match exactly
- Remove RFC label, as Zbc and Zbkb are ratified and
the cryptographic code was merged into openSSL
changes in v3:
- rebase on top of 6.3-rc2
- rebase on top of vector-v14 patchset
- add the missing Co-developed-by mentions to showcase
the people that did the actual openSSL crypto code
changes in v2:
- rebased on 6.2 + zbb series, so don't include already
applied changes anymore
- refresh code picked from openssl as that side matures
- more algorithms (SHA512, AES, SM3, SM4)

RISC-V: hook new crypto subdir into build-system
RISC-V: crypto: add accelerated GCM GHASH implementation
