[PATCH v6 00/14] support subsets of scalar crypto extension

[Weiwei Li <liweiwei@iscas.ac.cn>]

This patchset implements RISC-V scalar crypto extension v1.0.0 version instructions. 
Partial instructions are reused from B-extension.

Specification:
https://github.com/riscv/riscv-crypto

The port is available here:
https://github.com/plctlab/plct-qemu/tree/plct-k-upstream-v6

To test rvk implementation,  specify cpu argument with 'zks=true,zkn=true'  
or 
"zbkb=true,zbkc=true,zbkx=true,zknd=true,zkne=true,zknh=true,zksed=true,zksh=true,zkr=true" to enable  K-extension support.  This implementation can pass the ACT tests 
for K with our extended act support for qemu (available at 
https://github.com/plctlab/plct-qemu/tree/plct-k-upstream-v6-with-act)

v6:
* add reviewed-by tags
* rebase on riscv-to-apply.next

v5:
* split the big patches

v4:
* drop "x-" in exposed properties
* delete unrelated changes

v3:
* add extension check for SEED csr access

v2:
* optimize implementation for brev8, xperm, zip, unzip
* use aes related sbox array from crypto/aes.h
* move sm4_sbox to crypto/sm4.c, and share it with target/arm
