ACPI: DPTF: Add ACPI_DPTF Kconfig menu

Browse Source 
Add a Kconfig menu for Intel DPTF (Dynamic Platform and Thermal
Framework), put both the existing participant drivers in it and set
them to be built as modules by default.

While at it, do a few assorted cleanups for a good measure.

As a container for multiple power/thermal technologies, DPTF provides
a coordinated approach for different policies to effect the hardware
state of a system.
