ide: manage resources for PCI devices in ide_pci_enable() (take 3)

Browse Source 
* Reserve PCI BARs 0-3 (0-1 for single port controllers) in
  ide_pci_enable() and remove ide_hwif_request_regions() call
  from ide_device_add_all() (also cleanup resource management
  in scc_pata host driver).

* Fix handling of PCI BAR 4 in ide_pci_enable(), then cleanup
  ide_iomio_dma() (+ init_hwif_trm290() in trm290 host driver)
  and remove ide_release[_iomio]_dma().

v2:
* Fixup trm290 host driver.

v3:
* Because of scc_pata host driver changes we need to call
  pci_request_selected_regions() also in setup_mmio_scc().
