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.

* 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 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)"
