This is not related to cpuidle. For Exynos usually the cpuidle enters system sleep modes, so entire system is sleeping and devfreq does not work in that moment. However when power domains are off because of runtime PM, changing clocks may be completely ok. Many clocks are not part of the power domain itself. In the same time devfreq usually changes top level clocks which is also quite safe.
