This does not solve the problem that Russell mentioned: existing platforms
select PCI unconditionally, e.g. Iop13XX, some IXP, Orion, Shark
and more. At the very least, these would need to also select MIGHT_HAVE_PCI
to avoid the warning.

Typo: you certainly meant MIGHT_HAVE_PCI here.

We still need to agree on what it should be doing, but otherwise this
is what I had in mind.
