Pull ACPI updates from Rafael Wysocki:
 "These update the ACPICA code in the kernel to upstream revision
  20230331, fix the ACPI SBS driver and the evaluation of the _PDC
  method on Xen dom0 in the ACPI processor driver, update the ACPI
  driver for Intel SoCs and clean up code in multiple places.

  Specifics:

   - Update the ACPICA code in the kernel to upstream revision 20230331
     including the following changes:
       * Delete bogus node_array array of pointers from AEST table
         (Jessica Clarke)
       * Add support for trace buffer extension in GICC to the ACPI MADT
         parser (Xiongfeng Wang)
       * Add missing macro ACPI_FUNCTION_TRACE() for
         acpi_ns_repair_HID() (Xiongfeng Wang)
       * Add missing tables to astable (Pedro Falcato)
       * Add support for 64 bit loong_arch compilation to ACPICA (Huacai
         Chen)
       * Add support for ASPT table in disassembler to ACPICA (Jeremi
         Piotrowski)
       * Add support for Arm's MPAM ACPI table version 2 (Hesham
         Almatary)
       * Update all copyrights/signons in ACPICA to 2023 (Bob Moore)
       * Add support for ClockInput resource (v6.5) (Niyas Sait)
       * Add RISC-V INTC interrupt controller definition to the list of
         supported interrupt controllers for MADT (Sunil V L)
       * Add structure definitions for the RISC-V RHCT ACPI table (Sunil
         V L)
       * Address several cases in which the ACPICA code might lead to
         undefined behavior (Tamir Duberstein)
       * Make ACPICA code support flexible arrays properly (Kees Cook)
       * Check null return of ACPI_ALLOCATE_ZEROED in
         acpi_db_display_objects() (void0red)
       * Add os specific support for Zephyr RTOS to ACPICA (Najumon)
       * Update version to 20230331 (Bob Moore)

   - Fix evaluating the _PDC ACPI control method when running as Xen
     dom0 (Roger Pau Monne)

   - Use platform devices to load ACPI PPC and PCC drivers (Petr Pavlu)

   - Check for null return of devm_kzalloc() in fch_misc_setup() (Kang
     Chen)

   - Log a message if enable_irq_wake() fails for the ACPI SCI (Simon
     Gaiser)

   - Initialize the correct IOMMU fwspec while parsing ACPI VIOT
     (Jean-Philippe Brucker)

   - Amend indentation and prefix error messages with FW_BUG in the ACPI
     SPCR parsing code (Andy Shevchenko)

   - Enable ACPI sysfs support for CCEL records (Kuppuswamy
     Sathyanarayanan)

   - Make the APEI error injection code warn on invalid arguments when
     explicitly indicated by platform (Shuai Xue)

   - Add CXL error types to the error injection code in APEI (Tony Luck)

   - Refactor acpi_data_prop_read_single() (Andy Shevchenko)

   - Fix two issues in the ACPI SBS driver (Armin Wolf)

   - Replace ternary operator with min_t() in the generic ACPI thermal
     zone driver (Jiangshan Yi)

   - Ensure that ACPI notify handlers are not running after removal and
     clean up code in acpi_sb_notify() (Rafael Wysocki)

   - Remove register_backlight_delay module option and code and remove
     quirks for false-positive backlight control support advertised on
     desktop boards (Hans de Goede)

   - Replace irqdomain.h include with struct declarations in ACPI
     headers and update several pieces of code previously including of.h
     implicitly through those headers (Rob Herring)

   - Fix acpi_evaluate_dsm_typed() redefinition error (Kiran K)

   - Update the pm_profile sysfs attribute documentation (Rafael
     Wysocki)

   - Add 80862289 ACPI _HID for second PWM controller on Cherry Trail to
     the ACPI driver for Intel SoCs (Hans de Goede)"
