hw/pxb: introduce pxb-pcie expander for PCIe machines

Browse source 
The pxb-pcie is the counterpart of pxb for PCI express machines.
The new device re-uses the pxb code, but appears to the guests
as a different device. The pxb-pcie device does not have an internal
pci-pci bridge and exposes a PCIe root bus instead of a PCI one.
