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.
