Hi,
We disabled recording cpufreq stats when fast switching was introduced
to the cpufreq core as the cpufreq stats required to take a spinlock and
that can't be allowed (for performance reasons) on scheduler's hot path.
Here is an attempt to get rid of the lock and bring back the support.
--
In order to prepare for lock-less stats update, add support to defer any
updates to it until cpufreq_stats_record_transition() is called.

The cpufreq core handles the updates to policy->cur and recording of
cpufreq trace events for all the governors except schedutil's fast
switch case.
Move that as well to cpufreq core for consistency and readability.

Now that all the blockers are gone for enabling stats in fast-switching
case, enable it.

The locking isn't required anymore as stats can get updated only from
one place at a time. Remove it.

Thw qdisc_reset() should be done after rcu grace period, when there is
