[PATCH v3 1/6] pci_ids: Add Hygon Family 0x18 DF F3/F4 device IDs

[Lin Wang]

Add the PCI device IDs for the Data Fabric (DF) misc (function 3) and
link (function 4) devices on Hygon Family 0x18 processors.  These IDs
are used by Hygon DF node enumeration to discover and
identify DF instances on the system.

Coverage spans the supported Hygon Family 0x18 models (0x04-0x08):

  Model 0x04 (incl. mixed-silicon variant): F3=0x1463 F4=0x1464,
                                            F3=0x1493 F4=0x1494
  Model 0x05 through 0x08:                  F3=0x14b3 F4=0x14b4

Some values numerically match AMD DF IDs, but the IDs are matched as
vendor/device pairs with PCI_VENDOR_ID_HYGON; the explicit
Hygon-prefixed names keep enumeration independent of AMD device-ID
naming.  Like the AMD DF IDs they sit next to, they may be referenced
by further Hygon DF consumers over time.
