s390x/cpumodel: default enable bpb and ppa15 for z196 and later
Most systems and host kernels provide the necessary building blocks for
bpb and ppa15. We can reverse the logic and default enable those
features, while still allowing to disable it via cpu model.
So let us add bpb and ppa15 to z196 and later default CPU model for the
qemu 3.0 machine. (like -cpu z13). Older machine types (e.g.
s390-ccw-virtio-2.12) will retain the old value and not provide those
bits in the default model.
