driver. This used to be handled by cpufreq_drv_settings() but it's useful to get the type/flags separately from getting the settings. (For example, you don't have to pass an array of cf_setting just to find the driver type.) Use this new method in our in-tree drivers to detect reliably if acpi_perf is present and owns the hardware. This simplifies logic in drivers as well as fixing a bug introduced in my last commit where too many drivers attached.
