[PATCH v6-resend 06/17] PCI, PCI Hotplug: introduce slot_name helpers

[Alex Chiang <achiang@hp.com>]

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.
