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].
