Subject: [PATCH] powernow-k8: Add a kconfig dependency on acpi-cpufreq

Subject: [PATCH] powernow-k8: Add a kconfig dependency on acpi-cpufreq
Andreas reports in https://bugzilla.kernel.org/show_bug.cgi?id=51741
that with his Gentoo config, acpi-cpufreq wasn't enabled and powernow-k8
couldn't handoff properly to acpi-cpufreq leading to running without
P-state support (i.e., cores are constantly in P0).
To alleaviate that, we need to make powernow-k8 depend on acpi-cpufreq
so that acpi-cpufreq is always present.

This adds the CPUFreq driver for K8/early Opteron/Athlon64 processors.
Support for K10 and newer processors is now in acpi-cpufreq.
