Bartlomiej Zolnierkiewicz fd9bb53942 ide: add ->fixup method to ide_hwif_t
* Add ->fixup method to ide_hwif_t.

* Set hwif->fixup in ide_pci_setup_ports() to d->fixup.

* Use hwif->fixup in probe_hwif().

* Use probe_hwif_init() instead of probe_hwif_init_with_fixup() in
  ide_setup_pci_device().

* Add 'fixup' argument to ide_register_hw() and use it to set hwif->fixup,
  update all ide_register_hw() users accordingly.

* Convert ide-cs/delkin_cb host drivers to use ide_register_hw().

* Restore hwif->fixup in ide_hwif_restore().

* Remove ide_register_hw_with_fixup(), probe_hwif_init_with_fixup()
  and 'fixup' argument from probe_hwif().
