[PATCH] sata_nv: better irq handlers
nf2/3 and ck804 have irq status register. Implement better irq handler for those flavors of nv. This patch makes different flavors of nv controllers use different irq handlers by using separate port_info for each flavor. This change also makes following EH and hotplug updates easier to integrate. Signed-off-by: NTejun Heo <htejun@gmail.com> Signed-off-by: NJeff Garzik <jeff@garzik.org>
