[RFC PATCH 0/6] RISC-V: Add support for vector crypto extensions

[Christoph Muellner]

From: Christoph Müllner <christoph.muellner@vrull.eu>

This series add support for the vector crypto extensions:
* Zvkb
* Zvkg
* Zvkh[a,b]
* Zvkn
* Zvksed
* Zvksh

The implementation follows the version 20221220 of the specification,
which can be found here:
  https://github.com/riscv/riscv-crypto/releases/tag/v20221220

Note, that this specification is not frozen yet, meaning that
incompatible changes are possible.
Therefore, this patchset is marked as RFC and should not be considered
for upstream inclusion.

All extensions come with (passing) tests.

A branch with all patches applied can be found in this GitHub repo:
