Add IRQ coalescing to sata_mv (off by default). This feature can reduce total interrupt overhead for RAID setups in some situations, by deferring the interrupt signal until one or both of: a) a specified io_count (completed SATA commands) is achieved, or b) a specified time interval elapses after an IO completion. For now, module parameters are used to set the irq_coalescing_io_count and irq_coalescing_usecs (timeout) globally. These may eventually be supplemented with sysfs attributes, so that thresholds can be set on-the-fly and on a per-chip (or even per-host_controller) basis.
