s390/topology: enable / disable topology dynamically

Add a new sysctl file /proc/sys/s390/topology which displays if
topology is on (1) or off (0) as specified by the "topology=" kernel
parameter.

This allows to change topology information during runtime and
configuring it via /etc/sysctl.conf instead of using the kernel line
parameter.
