PCI hotplug: add pci_configure_slot()
This patch adds a new pci_configure_slot() function that programs the PCI bus characteristics for a newly-added device. This is based on code in pciehp_pci.c, but should be generic enough to be used by pciehp, shpchp, and acpiphp. The hotplug_params struct and the program_hpp_typeX() functions are based on the ACPI definitions, but they aren't really ACPI-specific, and there's no alternate implementation, so I don't see the need to abstract them yet.
