pc: limit 64 bit hole to 2G by default
It turns out that some 32 bit windows guests crash
if 64 bit PCI hole size is >2G.
Limit it to 2G for piix and q35 by default.
User may override default 64-bit PCI hole size by
using "pci-hole64-size" property.
Examples:
-global i440FX-pcihost.pci-hole64-size=4G
-global q35-pcihost.pci-hole64-size=4G
