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