[patch 1/2] fakephp: introduce pci_bus_add_device

[Jan Dittmer <jdittmer@ppp0.net>]

fakephp needs to add newly discovered devices to the global pci list.
Therefore seperate out the appropriate chunk from pci_bus_add_devices
to pci_bus_add_device to add a single device to sysfs, procfs
and the global device list.
