        src/sys/dev/pci: virtio_pci.c

Log Message:
virtio_pci_match: add TODO about PCI Revision ID.

The standard says:

  Transitional devices MUST have a PCI Revision ID of 0.

  Non-transitional devices SHOULD have a PCI Revision ID of 1 or higher.
  Drivers MUST match any PCI Revision ID value.

so we must not check the revision id for non-transitional devices.
The code in attach relies on the revision being specifically(NB!) 1 so
this calls for a revision, but I can't test this properly at the
moment, so just leave a reminder.  Comment change only.
