Merge branches 'acpi-scan' and 'acpi-processor'

Merge ACPI device enumeration updates and ACPI processor driver updates
for 6.8-rc1:

 - Add CSI-2 and DisCo for Imaging support to the ACPI device
   enumeration code (Sakari Ailus, Rafael J. Wysocki).

 - Adjust the cpufreq thermal reduction algorithm in the ACPI processor
   driver for Tegra241 (Srikar Srimath Tirumala, Arnd Bergmann).

 - Make acpi_proc_quirk_mwait_check() x86-specific (Rafael J. Wysocki).

* acpi-scan:
  ACPI: scan: Fix an error message in DisCo for Imaging support
  ACPI: property: Replicate DT-aligned u32 properties from DisCo for Imaging
  ACPI: property: Dig "rotation" property for devices with CSI2 _CRS
  ACPI: scan: Extract MIPI DisCo for Imaging data into swnodes
  device property: Add SOFTWARE_NODE() macro for defining software nodes
  ACPI: scan: Extract _CRS CSI-2 connection information into swnodes
  ACPI: scan: Extract CSI-2 connection graph from _CRS
  ACPI: property: Support using strings in reference properties

* acpi-processor:
  ACPI: arm64: export acpi_arch_thermal_cpufreq_pctg()
  ACPI: processor: reduce CPUFREQ thermal reduction pctg for Tegra241
  ACPI: processor: Provide empty stub of acpi_proc_quirk_mwait_check()
