the CPPC registers and ACPI _CPC objects.

The Continuous Performance Control Package is used to
describe the ACPI CPPC registers.

The generic register descriptor describes the localtion of a
fixed width register within any of the ACPI-defined address space.
This is needed to declare the ACPI CPPC registers.
