  - src/Makefile                       add romfs support

Renames:

- under boards/risc-v/k230/canmv230/src/ folder:
  - canmv_init.c from k230_appinit.c   making room for more k230 devices

Dropped:

- under arch/risc-v/src/k230/
  - k230_exception_m.S                 as hybrid mode not ready yet.

New files in boards/riscv/k230/canmv230:

- configs/knsh/defconfig                S-mode config
- scripts/ld-kernel.script              S-mode linker script
