Elliot Berman e50d7db612 [arch][riscv] Add support for running in supervisor mode ...

Add support for running LK in supervisor mode or machine mode.
- Macro-ify CSR access to use correct CSR # or use SBI call as req'd
- Add support to make SBI calls
- Split CLINT and lk timer abstraction so that RISC-V timer can use SBI
  as required.
- Add support for booting other harts as primary since hart0 on U540
  does not support S-mode. A map is used to get LK cpu number from
  hartid.
