Agree, unless some of the maintainers of this driver actually wants to
build simulation for it for testing or something, it's almost certainly
completely useless.

After all, the reason I enabled PCI on UML was to be able to test - in
simulation - PCI driver code in UML... Most certainly nobody wants to do
that here, so it's pointless to let the driver be compiled.

OTOH, as Christoph points out, that seems like a band-aid for some
really strange code, but it's probably the easiest way to get the build
issue fixed in the short term.
