arch/riscv: Add include/arch/barrier.h
mb() is used in src/arch/riscv/ and src/mainboard/emulation/*-riscv/. It is currently provided by atomic.h, but I think it fits better into barrier.h. The "fence" instruction represents a full memory fence, as opposed to variants such as "fence r, rw" which represent a partial fence. An operating system might want to use precisely the right fence, but coreboot doesn't need this level of performance at the cost of simplicity.
