Ah, there's no API, AFAICT.

Also, tools/power/cpupower/ uses sysfs too - you could reuse that
code if you don't feel like writing it yourself. The function is
cpufreq_get_hardware_limits()

Ok, technically, there is also a way to query the CPU's MSRs directly
but this is a bit more involved than reading sysfs nodes.

HTH.
