acpi: Add support for Collaborative Processor Performance Control (CPPC).
CPPC is the modern replacement for processor performance controls (P-states
and T-states). The _CPC method on a processor device contains information
about supported performance levels of the device.

setting the desired level using the machdep.cpufreq.cpuN.* sysctls. Note
that a "performance level" value is not guaranteed to represent a CPU
frequency, so treat the numbers reported as such.
