Currently there is no MMIO range over 4G reserved for PCI hotplug. Since the 32bit PCI hole depends on the number of cold-plugged PCI devices and other factors, it is very possible is too small to hotplug PCI devices with large BARs. Fix it by reserving 2G for I4400FX chipset in order to comply with older Win32 Guest OSes and 32G for Q35 chipset. Even if the new defaults of pci-hole64-size will appear in "info qtree" also for older machines, the property was not implemented so no changes will be visible to guests. Note this is a regression since prev QEMU versions had some range reserved for 64bit PCI hotplug.
