PCI: update pci_create_slot() to take a 'hotplug' param
Slot detection drivers can co-exist with hotplug drivers. The names of the detected/claimed slots may be different depending on module load order. For legacy reasons, we need to allow hotplug drivers to override the slot name if a detection driver is loaded first (and they find the same slots). Creating and overriding slot names should be an atomic operation, otherwise you get a locking nightmare as various drivers race to call pci_create_slot(). pci_create_slot() is already serialized by grabbing the pci_bus_sem. We update the API and add a 'hotplug' param, which is: set if the caller is a hotplug driver NULL if the caller is a detection driver pci_create_slot() does not actually use the 'hotplug' parameter in this patch. A later patch will add the logic that uses it.
