[PATCH v4 1/5] pci_ids: Add Hygon Family 0x18 DF F3/F4 device IDs

[Lin Wang]

Hygon Family 0x18 node discovery identifies Data Fabric misc (F3) and
link (F4) functions by PCI ID rather than a fixed PCI slot.

Models 0x04 use 0x1463/0x1464, with 0x1493/0x1494 on the mixed-silicon
variant. Models 0x05 through 0x08 use 0x14b3/0x14b4.

Some IDs have the same numeric values as AMD DF devices. PCI identity
also includes the vendor, so Hygon-prefixed names keep the two vendors'
definitions independent.
