Subject: [PATCH RESEND v8 0/6] riscv: add initial support for Canaan Kendryte K230

K230 is an ideal chip for RISC-V Vector 1.0 evaluation now. Add initial
support for it to allow more people to participate in building drivers
to mainline for it.

This kernel has been tested upon factory SDK [1] with
k230_evb_only_linux_defconfig and patched mainline opensbi [2] to skip
locked pmp and successfully booted to busybox on initrd with this log [3].
