Subject: [PATCH v2 0/7] riscv: add initial support for Canaan Kendryte K230

K230 is an ideal chip for testing RISC-V Vector 1.0 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].

[3] https://gist.github.com/cyyself/b9445f38cc3ba1094924bd41c9086176

Changes since v1:
- Patch dt-bindings in clint and plic
- Use enum in K230 compatible dt bindings
- Fix dts to pass `make dtbs_check`
- Add more details in commit message
