Merge additional APEI changes, ACPI updates related to device wakeup and
system restart and ACPI thermal driver cleanups for 6.1-rc1:

 - Fix a memory leak in APEI by avoiding to add do not add task_work to
   kernel threads running when an asynchronous error is detected (Shuai
   Xue).

 - Add ACPI support for handling system wakeups via GPIO wake capable
   IRQs in addition to GPEs (Raul E Rangel).

 - Make the system reboot code put ACPI-enabled systems into the S5
   (system off) state which is necessary for some platforms to work as
   expected (Kai-Heng Feng).

 - Make the white space usage in the ACPI thermal driver more consistent
   and drop redundant code from it (Rafael Wysocki).

  i2c: acpi: Use ACPI wake capability bit to set wake_irq
  ACPI: resources: Add wake_capable parameter to acpi_dev_irq_flags
  gpiolib: acpi: Add wake_capable variants of acpi_dev_gpio_irq_get

* acpi-reboot:
  PM: ACPI: reboot: Reinstate S5 for reboot
  kernel/reboot: Add SYS_OFF_MODE_RESTART_PREPARE mode

* acpi-thermal:
  ACPI: thermal: Drop some redundant code
  ACPI: thermal: Drop redundant parens from expressions
