ACPI / hotplug: Drop unfinished global notification handling routines
There are two global hotplug notification handling routines in bus.c, acpi_bus_check_device() and acpi_bus_check_scope(), that have never been finished and don't do anything useful, so drop them. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
