cpufreq / CPPC: Initialize policy->min to lowest nonlinear performance
Description of Lowest Perfomance in ACPI 6.1 specification states: "Lowest Performance is the absolute lowest performance level of the platform. Selecting a performance level lower than the lowest nonlinear performance level may actually cause an efficiency penalty, but should reduce the instantaneous power consumption of the processor. In traditional terms, this represents the T-state range of performance levels." Set the default value of policy->min to Lowest Nonlinear Performance to avoid any potential efficiency penalty.
