    s390x, sysconfig: Change maxcpus=1 to nr_cpus=1 for s390x
    
    IBM would strongly recommend for s390x to replace "maxcpus=1" with
    "nr_cpus=1" because with the "nr_cpus=1" kernel parameter only for one
    CPU the per-cpu data structures are allocated. This currently saves
    several MiB of memory.
    
    IBM (michael.holzheu at de.ibm.com) has confirmed this patch worked fine.
