[S390] register cpu devices for SMP=n
A kernel compiled with SMP=n will not register any cpu devices. The resulting kernel image will not boot with this error message: kernel BUG at fs/sysfs/group.c:65! Use GENERIC_CPU_DEVICES=y if SMP=n to get the missing cpu device. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
