ACPI: bus: change the prototype for acpi_get_physical_device_location

JIRA: https://issues.redhat.com/browse/RHEL-77309

commit 79f237b
Author: Ricardo Ribalda <ribalda@chromium.org>
Date: Mon, 16 Dec 2024 21:17:15 +0000

  It generally is not OK to use acpi_status and/or AE_ error codes
  without CONFIG_ACPI and they really only should be used in
  drivers/acpi/ (and not everywhere in there for that matter).

  So acpi_get_physical_device_location() needs to be redefined to return
  something different from acpi_status (preferably bool) in order to be
  used in !CONFIG_ACPI code.
