powerpc: Optimise smp_wmb
Change 2d1b2027626d5151fff8ef7c06ca8e7876a1a510 ("powerpc: Fixup
lwsync at runtime") removed __SUBARCH_HAS_LWSYNC, causing smp_wmb to
revert back to eieio for all CPUs. This restores the behaviour
intorduced in 74f0609526afddd88bef40b651da24f3167b10b2 ("powerpc:
Optimise smp_wmb on 64-bit processors").
