piix: fix 32bit pci hole
Make the 32bit pci hole start at end of ram, so all possible address space is covered. We used to try and make addresses aligned so they are easier to cover with MTRRs, but since they are cosmetic on KVM, this is probably not worth worrying about. Of course the firmware can use less than that. Leaving space unused is no problem, mapping pci bars outside the hole causes problems though.
