Virtex device tree generator proof of concept

ppx4xx support in arch/powerpc is still off in the distance, but here
is a proof of concept device tree generator for Xilinx virtex designs.
You pass the tool a .mhs file, and it spits out a .dts file.
Generated dts output is accepted by the dtc parser.  I've tested
against the ml403 reference designs and a custom design.

This code can also be viewed at:

Cheers,
