PCI: fix section mismatch on update_res()

Remark update_res from __init to __devinit as it is called also
from __devinit functions.

This patch removes the following warning message:

  WARNING: vmlinux.o(.devinit.text+0x774a): Section mismatch
  in reference from the function pci_root_bus_res() to the
  function .init.text:update_res()
  The function __devinit pci_root_bus_res() references
  a function __init update_res().
  If update_res is only used by pci_root_bus_res then
  annotate update_res with a matching annotation.
