Titan p2 used to specify class + subclass which is now replaced with
PCI_ID_ANY, I doubt this makes any difference at all.

The only runtime visible change I notice is with KERN_DEBUG being
visible. The card details are the same, it always prints

|parport1: PC-style at 0xc120 (0xc128), irq 11, using FIFO

However the ID that was used to detect the card is different:

| PCI parallel port detected: 1415:c118, I/O at 0xc120(0xc128), IRQ 11


| PCI parallel port detected: 9710:9805, I/O at 0xc120(0xc128), IRQ 11

The wrong id print is printed for all devices which come after
PCI_DEVICE_ID_OXSEMI_PCIe840_G in the id table because the code that
prints the ID table assumes one id per entry.

So we could
- drop printk
- use id->vendor + id->device instead
- do the last item + remove parport_pc_pci_cards and pass the data
  struct as data.
- nothing

any preferences?
