and clean up the handling of the common quirk wherein setting
INTX_DISABLE will mistakedly disable MSI generation for some
devices.

For devices without that problem, we want to keep the pci_intx() calls
in drivers/pci/msi.c because those help protect against devices
with the opposite problem.  Such devices always generate INTX
interrupts even when MSI is enabled, unless INTX_DISABLE is set.

Michael, please pay special attention to patch #3.  I think I
picked the correct PCI device IDs to match for the quirk
(5714* and 5780*) but it's possible we might need more elaborate
checks here.  It at least worked properly for the chips in my
Niagara system.

In addition to the Tigon3 cases, I added quirk entries for the
SB700/800 SATA chips and the IXP SB400 USB controllers.

I'm happy with this patch series. A quirk is better than a sledgehammer, and MSI-mode SATA is better than INTX-mode SATA :)
