Subject: [PATCH 2/9] ide: set hwif->dev in ide_init_port_hw()

* Add 'parent' field to hw_regs_t for optional parent device pointer (needed
  by macio PMAC IDE controllers) and set hwif->dev in ide_init_port_hw().

* Update au1xxx-ide.c, sgiioc4.c, pmac.c and setup-pci.c accordingly.

There should be no functional changes caused by this patch.
