The commit db8305ad explicitly adds pcie-root and pcie root ports for q35.
If the user selects i440FX chipset instead of Q35(default) from customize
dialog, The pre-defined pcie-root and ports cause failure when starting
i440fx VM installation because they're not applicable to i440fx..
It fails with below error message:
summary=Unable to complete install: 'XML error: The PCI controller with index='0'
must be model='pci-root' for this machine type, but model='pcie-root' was found instead'
details=Traceback (most recent call last):

libvirt.libvirtError: XML error: The PCI controller with index='0' must be
model='pci-root' for this machine type, but model='pcie-root' was found instead
This patch fixes it by removing the pcie-root and ports for i440fx in
apply_overview.
