target/ppc: Add POWER9 DD2.2 model
POWER9 DD2.1 and earlier had significant limitations when running KVM, including lack of "mixed mode" MMU support (ability to run HPT and RPT mode on threads of the same core), and a translation prefetch issue which is worked around by disabling "AIL" mode for the guest. These processors are not widely available, and it's difficult to deal with all these quirks in qemu +/- KVM, so create a POWER9 DD2.2 CPU and make it the default POWER9 CPU.
