Merge branch 'acpi-thermal'

Merge ACPI thermal zone driver updates for 6.8-rc1:

 - Use generic ACPI helpers for evaluating trip point temperature
   objects in the ACPI thermal zone driver (Rafael J. Wysockii, Arnd
   Bergmann).

 - Add Thermal fast Sampling Period (_TFP) support to the ACPI thermal
   zone driver (Jeff Brasen).

* acpi-thermal:
  ACPI: thermal_lib: include "internal.h" for function prototypes
  ACPI: thermal: Add Thermal fast Sampling Period (_TFP) support
  ACPI: thermal: Use library functions to obtain trip point temperature values
  ACPI: thermal_lib: Add functions returning temperature in deci-Kelvin
  thermal: ACPI: Move the ACPI thermal library to drivers/acpi/
