Add irq_flags to struct pata_platform_info
On some embedded platforms, such as blackfin, the gpio interrupt for IDE interface is designed to be triggered with high voltage. The gpio port should be configured properly by set_irq_type() when register the irq. This patch enable the generic pata platform driver to accept platform irq flags data.
