MIPS: bootm: prepare a flattened device tree for the kernel

Add the initial code to prepare a flattened device tree for
the kernel like relocating the FDT blob and fixing up the
/chosen and /memory nodes.

The final hand over to the kernel is not yet implemented. After
the community agreed on the MIPS boot interface for device trees,
the corresponding code will be added.
