Rafael J. Wysocki 46394fd017 ACPI / hotplug: Move container-specific code out of the core
Move container-specific uevents from the core hotplug code to the
container scan handler's .attach() and .detach() callbacks.

This way the core will not have to special-case containers and
the uevents will be guaranteed to happen every time a container
is either scanned or trimmed as appropriate.
