board/qemu/aarch64-virt/linux.config: enable VIRTIO_GPU driver
This driver is intended to be used by mesa virgl Gallium on the guest. virtio-gpu is enabled by adding "-device virtio-gpu-pci" on the qemu command line. It's detected by lspci and dmesg log: $ lspci 00:01.0 Display controller: Red Hat, Inc.
