PCI: Remove unnecessary __ref annotations
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. Relevant historical commits:
