Bjorn Helgaas 10874f5a00 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:

  54b956b903 Remove __dev* markings from init.h

  0ab2b57f8d PCI: fix section mismatch warning in pci_scan_child_bus
