ide: add struct ide_port_info instances to legacy host drivers

* Remove 'struct pci_dev *dev' argument from ide_hwif_setup_dma().

* Un-static ide_hwif_setup_dma() and add CONFIG_BLK_DEV_IDEDMA_PCI=n version.

* Add 'const struct ide_port_info *d' argument to ide_device_add[_all]().

* Factor out generic ports init from ide_pci_setup_ports() to ide_init_port(),
  move it to ide-probe.c and call it in in ide_device_add_all() instead of
  ide_pci_setup_ports().

* Move ->mate setup to ide_device_add_all() from ide_port_init().

* Add IDE_HFLAG_NO_AUTOTUNE host flag for host drivers that don't enable
  ->autotune currently.

* Setup hwif->chipset in ide_init_port() but iff pi->chipset is set
  (to not override setup done by ide_hwif_configure()).

* Add ETRAX host handling to ide_device_add_all().

* cmd640.c: set IDE_HFLAG_ABUSE_* also for CONFIG_BLK_DEV_CMD640_ENHANCED=n.

* pmac.c: make pmac_ide_setup_dma() return an error value and move DMA masks
  setup to pmac_ide_setup_device().

* Add 'struct ide_port_info' instances to legacy host drivers, pass them to
  ide_device_add() calls and then remove open-coded ports initialization.
