[PULL 42/61] target/riscv: Use RISCVException as return type for all csr ops |

From: LIU Zhiwei <zhiwei_liu@linux.alibaba.com>
The real return value type has been converted to RISCVException,
but some function declarations still not. This patch makes all
csr operation declarations use RISCVExcetion.
