[CPUFREQ] powernow-k8: Always compile powernow-k8 driver with ACPI support
powernow-k8 driver should always try to get cpufreq info from ACPI. Otherwise it will not be able to detect the transition latency correctly which results in ondemand governor taking a wrong sampling rate which will then result in sever performance loss. Let the user not shoot himself in the foot and always compile in ACPI support for powernow-k8. This also fixes a wrong message if ACPI_PROCESSOR is compiled as a module and #ifndef CONFIG_ACPI_PROCESSOR path is chosen.
