[CPUFREQ][2/2] preregister support for powernow-k8
This patch provides support for the _PSD ACPI object in the Powernow-k8
driver. Although it looks like an invasive patch, most of it is
simply the consequence of turning the static acpi_performance_data
structure into a pointer.
AMD has tested it on several machines over the past few days without issue.
