defconfig: kona: Enable CPUFREQ Time in State Stats config on kona

This config exports CPU time-in-state information through procfs. The
procfs entries /proc/uid_time_in_state, /proc/uid_concurrent_active_time
and /proc/uid_concurrent_policy_time are needed for the compliance tests
to pass on kona.
