dt: add helpers for multi-cell adds

We have device tree helpers that allow us to create single cell (u32)
wide properties. However, when creating properties that contain an array of
cells, we need to jump through hoops, manually passing in an array with
converted endianness....

dt: add helper for phandle references

Phandles are the fancy device tree name for "pointer to another node".
To create a phandle property, we most likely want to reference to the
node we're pointing to by its path. So create a helper that allows
us to do so....

dt: add helper for phandle enumeration

This patch adds a helper to search for a node's phandle by its path. This
is especially useful when the phandle is part of an array, not just a single
cell in which case qemu_devtree_setprop_phandle would be the easy choice....

device tree: add add_subnode command

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

device tree: add nop_node

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....

Allow qemu_devtree_setprop() to take arbitrary values

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,...

Implement device tree support needed for Bamboo emulation

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...
