- convert ->isa_ports into ->flags (IDEPCI_FLAG_ISA_PORTS)
- add IDEPCI_FLAG_{OBS_FORCE_PDC,FORCE_MASTER} flags
and use them in setup-pci.c
- use struct pci_dev ->vendor and ->device fields directly
in generic.c and serverworks.c
- remove no longer needed debug checks (dev->device != d->device)
- remove ->vendor and ->device fields from ide_pci_device_t
- misc cleanups
