The only things the platform needs are GIC, timers, memory and a CPU. Furthermore, the location, size, frequency etc properties of these aren't fixed, so a dts would be fairly useless because it will probably not match the particular mach-virt instance you're targetting. For kvmtool, I've been generating the device-tree at runtime based on how kvmtool is invoked and it's been working pretty well so far.
