Investigate support for intel_cpufreq

[pyamsoft]

Is this common enough that instead of acpi-cpufreq or intel_pstate users see this scheduler instead?

Since this is an acpi-cpufreq like scheduler I assume we can use a lot of the existing acpi cpufreq paths and logic and just change the base from acpi- to intel_ but it's just a theory.

I do not have an Intel CPU that uses this scheduler.
