Christoph Müllner 7543bb3a69 riscv: SM4: Provide a Zvksed-based implementation
The upcoming RISC-V vector crypto extensions feature
a Zvksed extension, that provides SM4-specific instructions.
This patch provides an implementation that utilizes this
extension if available.

Tested on QEMU and no regressions observed.
