riscv: Access CSRs using CSR numbers
We should prefer accessing CSRs using their CSR numbers
because:
1. It compiles fine with older toolchains.
2. We can use latest CSR names in #define macro names of CSR
numbers as-per RISC-V spec.
3. We can access newly added CSRs even if toolchain does not
recognize newly added CSRs by name.
This commit is inspired from Linux kernel commit a3182c91ef4e
("RISC-V: Access CSRs using CSR numbers").
