By default ata_host_activate() expects a valid IRQ in order to
successfully register the host. This patch enables a special case
for registering polling-only hosts that either don't have IRQs
or have buggy IRQ generation (either in terms of handling or
sensing), which otherwise work fine.
Hosts
Some SH boards (old R2D-1 boards) have generally not had working CF
under libata, due to both buswidth issues (handled by Aoi Shinkai
in 43f4b8c7578b928892b6f01d374346ae14e5eb70), and buggy interrupt
controllers. For these sorts of boards simply disabling the IRQ and
polling ends up working fine.

sata_qstor likes to disable the chip on module unload,
so it provides a libata host_stop method to do this.
But in recent kernels, this routine is now called too late,
after the PCI mmio resources have already been released.
Which produces an oops.

sata_qstor workaround for spurious interrupts.
The qstor hardware generates spurious interrupts from time to time when
switching
in and out of packet mode. These eventually result in the IRQ being disabled,
which kills other devices sharing this IRQ with us.
This workaround isn't perfect, but

So I'll change the check to IRQ#0 == invalid, but if that's to be

ripped out and set to 0. This way at least people are getting screwed

Yeah. No docs whatsoever, but there's more than a few users
of it out there.
So how do we handle devices that don't support PIO4 ?
Other than the speed handling mystery the port is trivial.
