Laszlo Ersek bba734ab4c OvmfPkg/PlatformPei: provide 10 * 4KB of PCI IO Port space on Q35
This can accommodate 10 bridges (including root bridges, PCIe upstream and
downstream ports, etc -- see
<https://bugzilla.redhat.com/show_bug.cgi?id=1333238#c12> for more
details).

10 is not a whole lot, but closer to the architectural limit of 15 than
our current 4, so it can be considered a stop-gap solution until all
guests manage to migrate to virtio-1.0, and no longer need PCI IO BARs
behind PCIe downstream ports.
