We should make the hole larger to get more pci i/o address space below
4G, especially as q35 needs a good chunk of it for mmconfig.
I think at least 0xc0000000, maybe even 0xb0000000. The later would
allow to place mmconfig @ 0xb0000000, one big 512MB pci bar @ 0xc0000000
(think gfx card pass-through) and all the remaining little stuff above
0xe0000000.
cheers,
Gerd
