ACPI fixes for 6.0-rc3

Browse Source 
- Prevent acpi_thermal_cpufreq_exit() from attempting to remove
    the same frequency QoS request for multiple times (Riwen Lu).
 
  - Fix type detection for integer ACPI device properties (Stefan
    Binding).
 
  - Avoid emitting false-positive warnings when processing ACPI
    device properties and drop the useless default case from the
    acpi_copy_property_array_uint() macro (Sakari Ailus).

Merge tag 'acpi-6.0-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull ACPI fixes from Rafael Wysocki:
 "These fix issues introduced by recent changes related to the handling
  of ACPI device properties and a coding mistake in the exit path of the
  ACPI processor driver.

  Specifics:

   - Prevent acpi_thermal_cpufreq_exit() from attempting to remove
     the same frequency QoS request multiple times (Riwen Lu)

   - Fix type detection for integer ACPI device properties (Stefan
     Binding)

   - Avoid emitting false-positive warnings when processing ACPI
     device properties and drop the useless default case from the
     acpi_copy_property_array_uint() macro (Sakari Ailus)"

* tag 'acpi-6.0-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
  ACPI: property: Remove default association from integer maximum values
  ACPI: property: Ignore already existing data node tags
  ACPI: property: Fix type detection of unified integer reading functions
  ACPI: processor: Remove freq Qos request for all CPUs
