ff2f6b2478 drivers/intel/dptf: Add current participant Devices to DSDT
In this DPTF implementation, the participant device objects are written
into the DSDT with only minimal Names attached (_HID/_ADR, _STA, _UID,
PTYP, and _STR). All other Methods & Names will be written into the
SSDT. If a device is not used in any policy, then its _STA is set to
return 0 ("off").

BUG=b:143539650
TEST=Compiles.

103bd5e4bb dptf: Introduce new paradigm for configuring DPTF parameters
Currently, configuring and reviewing DPTF parameters is difficult
because DPTF tables and methods are defined in static ASL files, and are
littered with #ifdefs which both define parameters and influence
behavior (e.g., whether a method is included or not). This patch train
is an effort to bring DPTF support to our ACPI DSDT/SSDT generation
framework.

This first patch is very minimal, and includes only creation of the
DPTF device (in the DSDT).

BUG=b:143539650
TEST=compiles (later tests get more comprehensive).
