acorn32: Partial __cpu_simple_lock membar audit.
For __cpu_simple_unlock, __insn_barrier is absolutely required.
Whether we need a stronger memory barrier, I don't know offhand and
I'm not sure what the right architecture manual to consult is -- it's
not clear why this isn't just using the generic arm lock.h.
