This fixes the behavior of the scaling_max_freq and scaling_min_freq sysfs files in systems which had turbo disabled by the BIOS. Caleb noticed that the HWP is programmed to operate in the wrong P-state range on his system when the CPUFREQ policy min/max frequency is set via sysfs. This seems to be because in his system intel_pstate_get_hwp_max() is returning the maximum turbo P-state even though turbo was disabled by the BIOS, which causes intel_pstate to scale kHz frequencies incorrectly e.g. setting the maximum turbo frequency whenever the maximum guaranteed frequency is requested via sysfs.
