Pull more ACPI updates from Rafael Wysocki:
"Additional ACPI updates.

These update the ACPICA code in the kernel to the 20200326 upstream
revision, fix an ACPI-related CPU hotplug deadlock on x86, update
Intel Tiger Lake device IDs in some places, add a new ACPI backlight
blacklist entry, update the "acpi_backlight" kernel command line
switch documentation and clean up a CPPC library routine.

* acpiExec namespace init file fixes (Bob Moore)
* Addition of NHLT to the known tables list (Cezary Rojewski)
* Conversion of PlatformCommChannel ASL keyword to PCC (Erik
Kaneda)
* acpiexec cleanup (Erik Kaneda)
* WSMT-related typo fix (Erik Kaneda)
* sprintf() utility function fix (John Levon)
* IVRS IVHD type 11h parsing implementation (Michał Żygowski)
* IVRS IVHD type 10h reserved field name fix (Michał Żygowski)

- Fix ACPI-related CPU hotplug deadlock on x86 (Qian Cai)

- Fix Intel Tiger Lake ACPI device IDs in several places (Gayatri
Kammela)

- Add ACPI backlight blacklist entry for Acer Aspire 5783z (Hans de
Goede)

- Fix documentation of the "acpi_backlight" kernel command line
switch (Randy Dunlap)
