[Qemu-arm] [PATCH v7 14/20] hw/arm/virt: Store the PCI host controller dt phandle

[Eric Auger <eric.auger@redhat.com>]

Let's allocate a phandle for the PCI host controller dt
node and store this latter in the Virt Machine State. This
will simplify fdt operations when we bind smmu and PCI host
controller.
