s390/configs: Enable cpuidle driver on s390
Enable cpuidle infrastructure, idle governor and s390 cpuidle driver by
default. They can be disabled via config options before compile or via
setting cpuidle.off kernel commandline option. When cpuidle.off=1 set,
given architecture's specific implementation is used as a fallback without
any governor or idle state support.
During runtime individual states of cpuidle driver can also be disabled
via sysfs attributes:
echo 1 > /sys/devices/system/cpu<N>/cpuidle/state<M>/disable
