[00/19] ppc: QOM'ify 405 board

Hello,

Here is large series QOM'ifying the PPC405 board. It introduces a new
generic machine and SoC models, converts the current device models to
QOM and populates the SoC. The process is quite mechanical without too
much issues to handle. The noisy part is the initial patch introducing
the SoC realize routine. 

What's left ?

* The DCR read/writre handler are attached in table to the CPU
  instance. We could probably rework the whole with a specific address
  space and memory regions handling the implemented registers. I don't
  think this is necessary.

* the SDRAM mappings are very baroque and certainly could be simplified.
  I think we should QOMify the ppc440 machines before addressing this
  part.

Thanks,

C.
