    x86: enable CPU frequency scaling
    
    CPU frequency scaling enables the operating system to scale the CPU
    frequency up or down in order to save power. CPU frequencies can be
    scaled automatically depending on the system load, in response to ACPI
    events, or manually by userspace programs.
