We want to be able to create subnodes in our device tree, so export it through
the qemu device tree abstraction framework.

We have a qemu internal abstraction layer on FDT. While I'm not fully convinced
we need it at all, it's missing the nop_node functionality that we now need
on e500. So let's add it and think about the general future of that API later.

Currently qemu_devtree_setprop() expects the new property value to be
given as a uint32_t *. While property values consisting of u32s are
common, in general they can have any bytestring value.
Therefore, this patch alters the function to take a void * instead,
allowing callers to easily give anything as the property value.

To implement the -kernel, -initrd, and -append options, 4xx board emulation
must load the guest kernel as if firmware had loaded it. Where u-boot would be
the firmware, we must load the flat device tree into memory and set key fields
such as /chosen/bootargs.
This patch introduces a dependency on libfdt for flat device tree support.
