For now, e.g. host-s390-cpu wasn't exposed to the user. cpu-add, -cpu
and the CPU model qmp interfaces didn't care about the actual type,
as that information was hidden.

This changed with CPU hotplug via device_add. Now the type is visible to
the user. Before we get that supported in a stable version, this is our
last chance to change it.

So change it form "s390-cpu" to "s390x-cpu", to match the architecture
name. Example names are then e.g. z14-s390x-cpu or qemu-s390x-cpu.

Basically fine for me ... but just to be sure: Did you test whether
migration still works fine from older versions to a version that
contains this patch?

Very basic migration testing (initrd guest with 4 cpus). That name
should not pup up in the migration stream.

If there are no objections, Christian can you pick this up (fixing the
typo) so we get this into 2.11?
