acpi-cpufreq: Add support for modern AMD CPUs
The programming model for P-states on modern AMD CPUs is very similar to that of Intel and VIA. It makes sense to consolidate this support into one driver rather than duplicating functionality between two of them. This patch adds support for AMDs with hardware P-state control to acpi-cpufreq.
