Ideally, we'd simply fix this to build as a module, but it's not clear
how to do that now that the ecam accessors have been split out into
their own file. A liberal sprinkling of EXPORT_SYMBOL might work, but
it's a bit grotty.

David, Jayachandran -- do you have any desire to build your PCI host
controller drivers as modules?
