    arm64: add more barrier support
    
    The load-acquire/store-release operations (including exclusive
    variants) form a basis for atomic operations. Also remove
    the dmb, dsb, and isb functions from lib_helpers as barrier.h
    already included these. Lastly, utilize barrier.h.
    
    BUG=chrome-os-partner:31761
    BRANCH=None
    TEST=Built and ran SMP bringup using barriers.
