This actually breaks MIPS builds. MIPS builds the .dtbs in the same
directory as the .dts files. Everyone else has a dts/ subdirectory,
which is admittedly a bit insane, but until things are resolved I've
dropped the above MIPS hunks.

MIPS /could/ be changed to also use a dts directory, but I'd actually
rather if someone could make all the other platforms build the dtbs in
the same directory. I've looked at it briefly, but I haven't figured
out all the make magic needed to do it nicely.
