PCI: disable pci_find_device warnings when deprecated pci functions are enabled

Browse Source 
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.

* @device: PCI device id to match, or %PCI_ANY_ID to match all device ids
* @from: Previous PCI device found in search, or %NULL for new search.

* Iterates through the list of known PCI devices. If a PCI device is found
* with a matching @vendor and @device, a pointer to its device structure is
* returned. Otherwise, %NULL is returned.
* A new search is initiated by passing %NULL as the @from argument.
* Otherwise if @from is not %NULL, searches continue from next device
* on the global list.
*
* NOTE: Do not use this function any more; use pci_get_device() instead, as
* the PCI device returned by this function can disappear at any moment in
* time.
