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.
