cpufreq: Remove support for hardware P-state chips from powernow-k8
These chips are now supported by acpi-cpufreq, so we can delete all the
code handling them.
Andre: Tighten the deprecation warning message. Trigger load of
acpi-cpufreq and let the load of the module finally fail.
This avoids the problem of users ending up without any cpufreq support
after the transition.
