arch-riscv: Update CSR implementations
This patch updates the CSRs to match the RISC-V privileged specification version 1.10. As interrupts, faults, and privilege levels are not yet supported, there are no meaninful side effects that are implemented. Performance counters are also not yet implemented, as they do not have specifications. Currently they act as cycle counters. Note that this implementation trusts software to use the registers properly. Access protection, readability, and writeability of registers based on privilege will come in a future patch.
