This reverts commit 672bd9bee5c0045694ef20fe3e2f7a003bef0edd.
Reason for revert: Gmeet resolution dropped. When system starts
Gmeet video call, it uses the hardware accelerated encoder as per
the expectation. But, as soon as another system connects to the call,
the immediate fallback observed from hardware to software encoder.
Due to this, Gmeet resolution dropped from 720p to 180p.
Currently, this issue observed on AlderLake-N SoC based fanless
platforms. This issue is not seen on fan based systems.
BUG=b:246535768,b:235254828
BRANCH=None
TEST=Built and tested on Alderlake-N systems. With this revert
Gmeet resolution drop not observed.

This adds OEM variables feature under DPTF as per BWG doc #541817. Using
this, platform vendors can expose an array of OEM-specific values as OEM
variables to be used in determining DPTF policy. These are obtained via
the ODVP method, and then simply exposed under sysfs. In addition, these
gets updated when a notification is received or when the DPTF policy is
changed by userspace.

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.

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
can pick different rates in order to passively cool (or not) the
system.

This patch adds support for DPTF Critical Policies, which are consist
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.

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).
