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. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
