[PATCH] libata: interrupt driven pio for LLD
libata.h:
libata-core:
Add ATA_FLAG_PIO_POLLING flag for LLDs that expect interrupt for
command completion only.
sata_nv.c:
sata_vsc.c:
irq handler is wrapper around ata_host_intr(), can handle PIO interrupts.
sata_promise.c:
sata_sx4.c:
sata_qstor.c:
sata_mv.c:
Private irq handler.
Polling mode ATA_FLAG_PIO_POLLING used for compatibility.
