When there are more nodes than memory available to put the minimum
allowed memory by node, all the memory is put on the last node.

This series introduces a new MachineState function to
distribute equally the memory across the nodes
without breaking compatibility with previous
machine types.

The new function uses an error diffusion algorithm to
distribute the memory across the nodes.

As the memory alignment for pseries is 256MB and for the others
is only 8MB, we introduce this change only for pseries-2.10
