Please ignore this patch. I send it again with correct version in subject.

It seems it's in Mathias' tree, never the less, see also below.

+#define PCI_DEVICE_ID_CADENCE				0x17CD

First of all this is misleadig as this is VENDOR_ID, second, there is official
ID constant for Cadence in pci_ids.h.

#define PCI_VENDOR_ID_CDNS              0x17cd


Thanks, fixed and rebased.
