The one important thing that the ide_init_hwif function handles for one
of my boards (and for the sandpoint) is the knowledge that the irqs are
14 and 15. If left to its own devices the pci-ide code  will assume that
both channels are on the same irq, which leaves the second channel
running without interrupts.

But I'd be happy with any simpler way of communicating "just use 14 and
15" to the pci-ide driver.
