alpha_platform_pci_*_intr is what I went with similar to the IDE intr
functions.

Well.... I did this, but probably NISA should be checked in
alpha_platform_pci_*_intr. I tried to test it, but right now you can't
build a kernel without ISA support. I did manage to pair down GENERIC to
a kernel without any ISA devices or ISA support, but I still get several
link errors at the end of the build in several chipset drivers, and also
for things like 'comconsole' in a lt of drivers. So, getting a non-ISA
compile will take a good chunk of work after this if people want
it. Unless there are any objections, I'll commit the latest patch (at the
normal place) when I get back from my last final in a few hours.
