Sean Anderson b8bc120927 riscv: Add option to support RISC-V privileged spec 1.9 ... Some older processors (notably the Kendryte K210) use an older version of the RISC-V privileged specification. The primary changes between the old and new are in virtual memory, and in the merging of three separate counter enable CSRs. Using the new CSR on an old processor causes an illegal instruction exception. This patch adds an option to use the old CSRs instead of the new one.
