The Kendryte K210 follows RISC-V v1.9 spec so MTVAL has instruction address (instead of instruction encoding) on illegal instruction trap. To handle above case, we fix sbi_illegal_insn_handler() without any impact on RISC-V v1.10 (or higher) systems. This achieved by exploiting the fact that program counter (and instruction address) is always 2-byte aligned in RISC-V world.
