PCI, PCI Hotplug: introduce slot_name helpers

Browse Source 
In preparation for cleaning up the various hotplug drivers
such that they don't have to manage their own 'name' parameters
anymore, we provide the following convenience functions:

	pci_slot_name()
	hotplug_slot_name()

These helpers will be used by individual hotplug drivers.
