libata: clean up port_ops->sff_irq_clear()
->sff_irq_clear() is called only from SFF interrupt handler, so there
is no reason to initialize it for non-SFF controllers. Also,
ata_sff_irq_clear() can handle both BMDMA and non-BMDMA SFF
controllers.
This patch kills ata_noop_irq_clear() and removes it from base
port_ops and sets ->sff_irq_clear to ata_sff_irq_clear() in sff
port_ops instead of bmdma port_ops.
