cpufreq / intel_pstate: Change to disallow module build
Load order is important in order for intel_pstate to take over as the default scaling driver from acpi-cpufreq. If both are built-in, acpi-cpufreq uses late_initcall() and intel_pstate uses device_initcall() so it will be able to register as the scaling before acpi-cpufreq for the processors supported by intel_pstate. If acpi-cpufreq is built as a module then intel_pstate still gets first option to become the scaling driver.
