cpu hotplug: s390 doesn't support additional_cpus anymore.
s390 doesn't support the additional_cpus kernel parameter anymore since a
long time. So we better update the code and documentation to reflect

In the event BIOS doesn't mark such hot-pluggable cpus as disabled entries, one could use this parameter "additional_cpus=x" to represent those cpus in the cpu_possible_map. -s390 uses the number of cpus it detects at IPL time to also the number of bits -in cpu_possible_map.
