[U-Boot] [PATCH 17/30] riscv: implement the invalidate_icache_* functions

Implement the functions invalidate_icache_range() and invalidate_icache_all(). RISC-V does not have instructions for explicit cache-control. The functions in this patch are implemented with the memory ordering instruction for synchronizing the instruction and data streams. This may be implemented
