Merge branches 'acpi-tables', 'acpi-numa', 'acpi-sysfs', 'acpi-cppc', 'acpi-thermal' and 'acpi-battery'

Merge ACPI tables parsing code update, NUMA-related ACPI update, CPPC
documentation update, ACPI sysfs attributes handling update and ACPI
thermal and battery drivers updates for 5.17-rc1:

 - Add AEST to the list of known ACPI table signatures (Shuuichirou
   Ishii).

 - Make ACPI NUMA code take hotpluggable memblocks into account when
   CONFIG_MEMORY_HOTPLUG is not set (Vitaly Kuznetsov).

 - Use default_groups in kobj_type in the ACPI sysfs code (Greg
   Kroah-Hartman).

 - Rearrange _CPC structure documentation (Andy Shevchenko).

 - Drop an always true check from the ACPI thermal driver (Adam
   Borowski).

 - Add new "not charging" quirk for Lenovo ThinkPads to the ACPI
   battery driver (Thomas Weißschuh).
