libata: make sff_irq_on() method optional
Now, with the introduction of the sff_set_devctl() method, we can use it in sff_irq_on() method too -- that way its implementations in 'pata_bf54x' and 'pata_scc' become virtually identical to ata_sff_irq_on(). The sff_irq_on() method now becomes quite superfluous, and the only reason not to remove it completely is the existence of the 'pata_octeon_cf' driver which implements it as an empty function. Just make the method optional then, with ata_sff_irq_on() becoming generic taskfile-bound function, still global for the 'pata_bf54x' driver to be able to call it from its thaw() and postreset() methods. While at it, make the sff_irq_on() method and ata_sff_irq_on() return 'void' as the result is always ignored anyway.
