Add virtio-net and virtio-9p devices to the devicetree without the status set. This ensures that the MMIO frame is set, and it is not fatal to start the driver initialisation procedure, which will typically bail out if it finds zero virtqueues. Add the virtio-rng device with status disabled. The disabled status is chosen because the FVP models have only supported this since 2022 and older models would trigger an external abort when trying to access or probe this MMIO region. This is included by the fvp-base devicetrees.
