cpufreq governors broken with !CONFIG_SMP?

While working on a few patches for schedutil I noticed that the CFS
cpufreq hooks depend on PELT, which depends on CONFIG_SMP.

I compiled and ran a UP kernel with intel_pstate. Running a cpu-bound
task did not result in the frequency increasing beyond fmin. For some reason
ondemand is working for me with the same test, not sure why yet.

It appears dbs/intel-pstate/schedutil have a dependency on CONFIG_SMP
now. Or am I missing something?
