riscv/barrier: Define __{mb,rmb,wmb}
Introduce __{mb,rmb,wmb}, and rely on the generic definitions for
{mb,rmb,wmb}. Although KCSAN is not supported yet, the definitions can
be made more consistent with generic instrumentation. Also add a space
to make the changes pass check by checkpatch.pl.
Without the space, the error message is as below:
ERROR: space required after that ',' (ctx:VxV)
26: FILE: arch/riscv/include/asm/barrier.h:23:
+#define __mb() RISCV_FENCE(iorw,iorw)
