[PATCH v2 0/3] RISC-V: Support Scalar Cryptography extension

[jiawei]

This patch is support Scalar Cryptography extension(k-ext v1.0.0-rc5) as
binutils part, you can find gcc patches part in https://github.com/WuSiYu/riscv-gcc/tree/trunk-crypto-rebase by siyu@isrc.iscas.ac.cn.

The first patch fix the order check with 'z' begin sub-extension, it set 'zb' before 'zk' as a right case. Some instruction in 'zbkb' and 'zbkc' is both used by Bitmanip and Scalar Cryptography extension, we just redefine the class with them. 

Here is the github repo link contain this patch: https://github.com/pz9115/riscv-binutils-gdb/commits/k-ext-rebase, the old version of this work is form https://github.com/riscv-collab/riscv-binutils-gdb/pull/254, Thanks for Nelson Chu and Jim Wilson's review and help.
