[PATCH v7 03/15] cpufreq: Export intel_feature_detect

[Jason Andryuk <jandryuk@xxxxxxxxx>]

Export feature_detect as intel_feature_detect so it can be re-used by
HWP.

Signed-off-by: Jason Andryuk <jandryuk@xxxxxxxxx>
Acked-by: Jan Beulich <jbeulich@xxxxxxxx>
---
v4:
Add Jan's Ack

v3:
Remove void * cast when calling intel_feature_detect

v2:
export intel_feature_detect with typed pointer
Move intel_feature_detect to acpi/cpufreq/cpufreq.h since the
declaration now contains struct cpufreq_policy *.
