Some PCI functions used to be marked __devinit. When CONFIG_HOTPLUG was not set, these functions were discarded after boot. A few callers of these __devinit functions were marked __ref to indicate that they could safely call the __devinit functions even though the callers were not __devinit. But CONFIG_HOTPLUG and __devinit are now gone, and the need for the __ref annotations is also gone, so remove them.
