The prompts for the DPTF Kconfig options were not necessary, they should
be selected based on what DPTF implementation is being used, ASL files
or generated at runtime. It's not really meant to be fiddled with at
build-time. Also rewrite the help text for the _HID selection, to try
and make it more clear when to use y or n.

Missed one other scope operator in the DPTF cleanup. This one is for the
fan device, and without this fix, the kernel isn't able to properly
control the fan (it gets confused about whether it's ACPI 4+ compatible
or not).
BUG=b:149722146
TEST=verify /sys/class/thermal/cooling_zone0/max_state returns > 1,
and /sys/class/thermal/cooling_zone0/cur_state is writable, and writing
the value of `max_state` causes the fan to spin faster.

The previous DPTF patch train missed the proper scope operator around
all of the TSR options. Without this, the optional GTSH and/or _STR
Methods end up in the wrong scope.

In the initial DPTF refactor, the scope of the TCPU device was
incorrectly set as \_SB, instead of \_SB.PCI0. However, because of the
way that the acpi_inject_dsdt() callback currently works (it injects
contents before the dsdt.aml file), the Scope where the TCPU
device lives (\_SB.PCI0) doesn't exist yet. Therefore, to avoid playing
games with *when* things are defined in the DSDT, switch to defining all
of the DPTF devices in the SSDT.

This patch converts the current DPTF policies from static ASL files into
the new SSDT-based DPTF implementation. All settings are intended to be
copied exactly.

\_SB.DPTF.IDSP adverties to the DPTF daemon which policies the
implementation supports. Added a new acpigen function to figure out
which policies are used, and fills out IDSP appropriately.

DPTF has several options on how to control the fan (fine-grained speed
control, minimum speed change in percentage points, and whether or not
the DPTF device should notify the Fan if it detects low speed).
Individual TSRs can also set GTSH, which is the amount of hysteresis
inherent in the measurement, either from circuitry (if analog), or in
firmware (if digital).

This change adds support for emitting the PPCC table, which describes
the ranges available as knobs for DPTF to tune. It can support min/max
power, min/max time window for averaging, and the minimum adjustment size
(granularity or step size) of each power limit. The current implementation
only supports PL1 and PL2.

This change adds support for generating the _FPS table for the DPTF Fan
object. The table describes different levels of fan activity that may be
applied to the system in order to actively cool it. The information
includes fan speed at a (rough) percentage level, fan speed in RPM,
potential noise level in centibels, and power in mA.

This change generates the DPTF TCHG.PPSS table in the SSDT. This table
describes different charging rates which are available to use. DPTF

of Method definitions only. They are `_CRT` and `_HOT`, which are
defined as temperature thresholds that, when exceeded, will execute a
graceful suspend or a graceful shutdown, respectively.

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").

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).
