configs: Add a linux-x86-demo cell configuration

This demonstrates non-root Linux booting. It is targeting the QEMU
reference setup but can easily be tailored for physical setups as well.
The config contains an ivshmem device to demonstrate both PCI device
discovery and inter-cell communication. Of the four available CPUs in
the QEMU setup, 3 are assigned to the cell to show that SMP works.
