I think this might have broken bhyve - a fake PCIe capability is put
on the root port so that guests will use MSI/MSI-x, but otherwise it
looks like parallel PCI. Not exactly spec-compliant, but then neither
is most of the world of PCI/PCIe.
It may be worth #ifdef'ing this with powerpc.

There are a ton of ARM boards that need this too. You can find one-off
hacks all through the tree and one of the nice things about this change
is that all of those can be consolidated/removed now. If we are going to
have some #ifdef and special cases, it would be better to make them for
bhyve.
