ppc: qemu: Enable VirtIO NET support
By default the QEMU ppce500 machine connects a VirtIO NET to the PCI controller, although it can be replaced to an e1000 NIC via additional command line options. Now that we have switched over to DM PCI, VirtIO support becomes possible. This commit enables the support.
