They can be used as a generic PCIe root port and PCIe-to-PCI bridge,
they're not Intel-specific as long as your firmware doesn't care about
the vendor and device id.

I think it's quite likely that we'll use them, or at least ioh3420, on
any PCIe machine.  So you probably want to add ioh3420 to arm-softmmu
and aarch64-softmmu as well.  I don't know about i82801b11, but it
doesn't hurt to have it in ARM/AArch64 either.

Also, the same can be done for xio3130, so you can also limit that one
to x86 and ARM/Aarch64.
