[PATCH v2 RESEND 00/11] platform/x86/amd/pmf: Introduce AMD PMF Driver

[Shyam Sundar S K <Shyam-sundar.S-k@amd.com>]

AMD PMF Driver (a.k.a Platform Management Framework) provides a
centralized framework based on sensor inputs, OS hints, platform state
and APU metrics to dynamically manage perf, power and system thermals.

The goal of the driver is to enhance end user experience by making AMD
PCs smarter, quieter, power efficient by adapting to user behavior and
environment.

The larger goals include:

- Enable easy customization of smart PC solutions by OEMs.
- Provide a framework for OEMs to add in custom algorithms and solutions
- Improve standby and dynamic platform power through active power
  management of platform devices.

In this series, support for following features has been added.
- "Static Power Slider" meant to manage the power budget based on the
  power modes or the slider position.
- "Auto Mode" tracks the moving power average of the APU and takes
  intelligent decisions to switch between different modes.

v2 Resend:
-----------
- Patches from 9 to 11 were not sent due to wrong email address. Hence
  resending.

v1->v2:
-------
- optimize the ACPI path by having a common routine
  apmf_if_call_store_buffer()
- Simply Static slider interaction with platform_profile
- Remove CONFIG_DEBUG_FS stub code
- Drop changes introduced in platform_profile_get()
- Drop CnQF support. Will be sent as a patch-set later.
- Other code improvements
