This series reworks some pci hotplug handlers (except for s390, that will require more work but is not required for now).
1. Route all unplug calls via the hotplug handler when called from the unplug_request handler. This will be required to get multi-stage hotplug handlers running, but also makes sense on its own (just like we already did for some CPU/memory hotplug handlers). 2. Introduce some pre_plug handlers where it makes sense already. 3. Call the plug/pre_plug handler also for coldplugged devices. Especially pcihp is special as it overwrites hotplug handlers. This series will not yet factor out pre_plug/plug/unplug from pci device realize/unrealize functions, this will require more work but this series is also required first to get it running.
