Adds the ppt_* and nv_* tuning knobs that are available via WMI methods and adds proper min/max levels plus defaults. The min/max are defined by ASUS and typically gained by looking at what they allow in the ASUS Armoury Crate application - ASUS does not share the values outside of this. It could also be possible to gain the AMD values by use of ryzenadj and testing for the minimum stable value. The general rule of thumb for adding to the match table is that if the model range has a single CPU used throughout, then the DMI match can omit the last letter of the model number as this is the GPU model. If a min or max value is not provided it is assumed that the particular setting is not supported. for example ppt_pl2_sppt_min/max is not set. If a <ppt_setting>_def is not set then the default is assumed to be <ppt_setting>_max It is assumed that at least AC settings are available so that the firmware attributes will be created - if no DC table is available and power is on DC, then reading the attributes is -ENODEV.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
