This adds U-Boot syscon driver for SiFive's Core Local Interruptor (CLINT). The CLINT block holds memory-mapped control and status registers associated with software and timer interrupts. This driver implements the riscv_get_time() API as required by the generic RISC-V timer driver, as well as some other APIs that are needed for handling IPI.
