  [Cezanne/Renoir] Adjust uPEP for different _HID behavior

Bug description:
  Feature: Correct uPEP support for all current ACPI _HID for AMD s2idle
  Code: 

  Currently oem-5.10 carries hack ""platform/x86: force LPS0 functions
  for AMD"" which helps some RN platforms, but is not the correct
  solution.

  The code that is the correct solution has been submitted to linux-acpi:
  
https://lore.kernel.org/linux-acpi/f50c6baf-a780-7a58-4083-88d539342...@gmail.com/T/#t

  This will fix RN properly and will also add support for the different
  variations used for CZN for uPEP.

  Please replace hack in oem-5.10, and also apply this series for
  oem-5.13.
