libxl will create an emulated PCI device tree node in the device tree to enable the guest OS to discover the virtual PCI during guest boot. Emulated PCI device tree node will only be created when there is any device assigned to guest. A new area has been reserved in the arm guest physical map at which the VPCI bus is declared in the device tree (reg and ranges parameters of the node). Note that currently we are using num_pcidevs instead of c_info->passthrough to decide whether to create a vPCI DT node. This will be insufficient if and when ARM does PCI hotplug. Add this note inside libxl_create.c where c_info->passthrough is set.
