Subject: libata: add irq_flags to struct pata_platform_info
From: "Sonic Zhang" <sonic.adi@xxxxxxxxx>
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.
