PCI: disable pci_find_device warnings when deprecated pci functions are enabled
Shut off the long standing linux/drivers/pci/search.c:144: warning: 'pci_find_device' is deprecated (declared at linux/drivers/pci/search.c:136) linux/drivers/pci/search.c:144: warning: 'pci_find_device' is deprecated (declared at linux/drivers/pci/search.c:136) warnings that appear on every build when CONFIG_PCI_LEGACY is enabled. gcc warns for the use in EXPORT_SYMBOL I moved these to a separate file and disabled the warning in the Makefile for that file.
