[libata] Remove ->irq_ack() hook, and ata_dummy_irq_on()
* ->irq_ack() is redundant to what the irq handler already performs... chk-status + irq-clear. Furthermore, it is only called in one place, when screaming-irq-debugging is enabled, so we don't want to bother with a hook just for that. * ata_dummy_irq_on() is only ever used in drivers that have no callpath reaching ->irq_on(). Remove .irq_on hook from those drivers, and the now-unused ata_dummy_irq_on() Signed-off-by: Jeff Garzik <jeff@garzik.org>
