ACPI / hotplug: Introduce common hotplug function acpi_device_hotplug()
Modify the common ACPI device hotplug code to always queue up the same function, acpi_device_hotplug(), using acpi_hotplug_execute() and make the PCI host bridge hotplug code use that function too for device hot removal. This allows some code duplication to be reduced and a race condition where the relevant ACPI handle may become invalid between the notification handler and the function queued up by it via acpi_hotplug_execute() to be avoided.
