[Qemu-devel] [RFC PATCH v3 18/18] spapr: Add pseries-2.2 machine

[Alexey Kardashevskiy <aik@ozlabs.ru>]

This defines new "pseries" machine version 2.2 and make it a default
machine.

Since "pseries-2.2" does not have "ddw" compat properties set to off and
"pseries" becomes an alias of "presies-2.2" instead of 2.1, this
effectively enables DDW on both emulated and VFIO PHBs.
