libata: add init helpers including ata_pci_prepare_native_host()
These will be used to convert LLDs to new init model. * Add irq_handler field to port_info. In new init model, requesting IRQ is LLD's responsibility and libata doesn't need to know about irq_handler. Most LLDs can simply register their irq_handler but some need different irq_handler depending on specific chip. The added port_info->irq_handler field can be used by LLDs to select the matching IRQ handler in such cases. * Add ata_dummy_port_info. * Implement ata_pci_prepare_native_host(), a helper to alloc ATA host, acquire all resources and init the host in one go.
