Merge branches 'acpi-processor', 'acpi-hotplug', 'acpi-init', 'acpi-pm' and 'acpica' 

* acpi-processor:
  ACPI / scan: reduce log level of "ACPI: \_PR_.CPU4: failed to get CPU APIC ID"
  ACPI / processor: Return specific error value when mapping lapic id

* acpi-hotplug:
  ACPI / scan: Clear match_driver flag in acpi_bus_trim()

* acpi-init:
  ACPI / init: Flag use of ACPI and ACPI idioms for power supplies to regulator API

* acpi-pm:
  ACPI / PM: Use ACPI_COMPANION() to get ACPI companions of devices

* acpica:
  ACPICA: Remove bool usage from ACPICA.
