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.
