ide: allow host drivers to specify IRQ flags
* Add ->irq_flags field to struct ide_port_info and struct ide_host.
* Update host drivers and IDE PCI code to use ->irq_flags field.
* Convert init_irq() and ide_intr() to use host->irq_flags.
This fixes handling of shared IRQs for non-PCI hosts
and removes ugly ifdeffery from core IDE code.
