Modified Files:
        src/common/lib/libc/arch/aarch64/atomic: atomic_op_asm.h

Log Message:
fix atomic_sub_*(). it was (delta - *ptr), should be (*ptr - delta).
changing shared macro doesn't effect other atomic_ops because
(*ptr [+|^] delta) and (delta [+|^] *ptr) have same result.

atomic_sub_*() haven't used because non standard API?
