[Qemu-ppc] [PULL 12/62] target/ppc/spapr: Enable mitigations by default for pseries-4.0 machine type |

From: Suraj Jitindar Singh <address@hidden>
There are currently 3 mitigations the availability of which is controlled
by the spapr-caps mechanism, cap-cfpc, cap-sbbc, and cap-ibs. Enable these
mitigations by default for the pseries-4.0 machine type.
By now machine firmware should have been upgraded to allow these
settings.
