[PATCH 5/6] PM: Allow ACPI devices to suspend/resume asynchronously

From: Rafael J. Wysocki <rjw@sisk.pl>

Set async_suspend for all ACPI devices, so that they can be suspended
and resumed asynchronously with other devices they don't depend on in
a known way (i.e. devices which are not their parents or children and
to which they are not connected via struct pm_link objects).
