[PATCH 4/6] ide: use ide_init_port_hw() in setup-pci.c

[Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>]

* Move setting hwif->gendev.parent from ide_pci_setup_ports()
  to ide_hwif_configure().

* Always set hwif->io_ports in ide_hwif_configure().

* Use ide_init_port_hw() in ide_hwif_configure().
