[nicolas.ferre@...el.com: updated to new machine_desc structure]

Hi,
I come back to this patch in the process of collecting things that has been
left on the mailing-list.
Gregory, can you have a loot at it?
v3: update the machine_desc structure to match latest improvements.
v2: update against new common init
we must use it as we can detect the cpu type only after mapping
the system controler.
