[Qemu-ppc] [PATCH v2] spapr: Define a 2.1 pseries machine

[Alexey Kardashevskiy]

This adds a v2.1 machine to support backward compatibility
for newer macines in the case if they ever be implemented.

This adds a "pseries-2.1" machine as a child of the "pseries"
machine and only changes visible machine name.

Changes:
v2:
* removed .instance_size from the new class, the parent's .instance_size
will be used in this case
