device tree: add nop_node

Allow qemu_devtree_setprop() to take arbitrary values
Currently qemu_devtree_setprop() expects the new property value to begiven as a uint32_t *. While property values consisting of u32s arecommon, in general they can have any bytestring value.

Implement device tree support needed for Bamboo emulation
To implement the -kernel, -initrd, and -append options, 4xx board emulationmust load the guest kernel as if firmware had loaded it. Where u-boot would bethe firmware, we must load the flat device tree into memory and set key fields...
