Add the PCI product id for an Open FPGA Stack PCI card.

Is there a URL to the card ?

This PCIe Device IDs have registered by Intel.

INTEL_OFS is a generic name, pci id's map to specific cards

Is there a more specific name for this card ?

I think using INTEL_OFS is better, because INTEL_OFS is the Generic development platform can support multiple cards which using OFS specification,
like Intel PAC N6000 card.
