ACPI updates for 5.10-rc1

Browse Source 
- Add support for generic initiator-only proximity domains to
    the ACPI NUMA code and the architectures using it (Jonathan
    Cameron).
 
  - Clean up some non-ACPICA code referring to debug facilities from
    ACPICA that are not actually used in there (Hanjun Guo).
 
  - Add new DPTF driver for the PCH FIVR participant (Srinivas
    Pandruvada).
 
  - Reduce overhead related to accessing GPE registers in ACPICA and
    the OS interface layer and make it possible to access GPE registers
    using logical addresses if they are memory-mapped (Rafael Wysocki).
 
  - Update the ACPICA code in the kernel to upstream revision 20200925
    including changes as follows:
    * Add predefined names from the SMBus sepcification (Bob Moore).
    * Update acpi_help UUID list (Bob Moore).
    * Return exceptions for string-to-integer conversions in iASL (Bob
      Moore).
    * Add a new "ALL <NameSeg>" debugger command (Bob Moore).
    * Add support for 64 bit risc-v compilation (Colin Ian King).
    * Do assorted cleanups (Bob Moore, Colin Ian King, Randy Dunlap).
 
  - Add new ACPI backlight whitelist entry for HP 635 Notebook (Alex
    Hung).
 
  - Move TPS68470 OpRegion driver to drivers/acpi/pmic/ and split out
    Kconfig and Makefile specific for ACPI PMIC (Andy Shevchenko).
 
  - Clean up the ACPI SoC driver for AMD SoCs (Hanjun Guo).
 
  - Add missing config_item_put() to fix refcount leak (Hanjun Guo).
 
  - Drop lefrover field from struct acpi_memory_device (Hanjun Guo).
 
  - Make the ACPI extlog driver check for RDMSR failures (Ben
    Hutchings).
 
  - Fix handling of lid state changes in the ACPI button driver when
    input device is closed (Dmitry Torokhov).
 
  - Fix several assorted build issues (Barnabás Pőcze, John Garry,
    Nathan Chancellor, Tian Tao).
 
  - Drop unused inline functions and reduce code duplication by using
    kobj_to_dev() in the NFIT parsing code (YueHaibing, Wang Qing).
 
  - Serialize tools/power/acpi Makefile (Thomas Renninger).
