PPC: e500: Support dynamically spawned sysbus devices

For e500 our approach to supporting dynamically spawned sysbus devices is to
create a simple bus from the guest's point of view within which we map those
devices dynamically.

We allocate memory regions always within the "platform" hole in address
space and map IRQs to predetermined IRQ lines that are reserved for platform
device usage.

This maps really nicely into device tree logic, so we can just tell the
guest about our virtual simple bus in device tree as well.
