arch,alpha: Convert smp_mb__*() to the asm-generic primitives
The Alpha ll/sc primitives do not imply any sort of barrier; therefore the smp_mb__{before,after} should be a full barrier. This is the default from asm-generic/barrier.h and therefore just remove the current definitions. Signed-off-by: Peter Zijlstra <peterz@infradead.org> Acked-by: Paul E.
