If kvm fails to set a nonzero epoch index, then we must ultimately fail
the migration as this will result in a giant time leap backwards. This

target.
On failure the guest will resume normally on the original host machine.

Commit e996583eb3 ("s390x/css: activate ChannelSubSys migration",

machines starting 2.10, but it ended up effectively enabling it
only for 2.10 as the registration of the appropriate VMStateDescription
happens in ccw_machine_2_10_instance_options which does not get
called for machines more recent than 2_10.
Let us move the corresponding chunk of code (which conditionally enables
the migration based on the value of the corresponding class property) to
ccw_init, which is called for each virtio-ccw machine instance.

Some time ago we discussed that using "id" as property name is not the
right thing to do, as it is a reserved property for other devices and
will not work with device_add.
Switch to the term "core-id" instead, and use it as an equivalent to
"CPU address" mentioned in the PoP. There is no such thing as cpu number,
so rename env.cpu_num to env.core_id. We use "core-id" as this is the
common term to use for device_add later on (x86 and ppc).
We can get rid of cpu->id now. Keep cpu_index and env->core_id in sync.
cpu_index was already implicitly used by e.g. cpu_exists(), so keeping
both in sync seems to be the right thing to do.
cpu_index will now no longer automatically get set via
cpu_exec_realizefn(). For now, we were lucky that both implicitly stayed
in sync.
Our new cpu property "core-id" can be a static property. Range checks can
be avoided by using the correct type and the "setting after realized"
check is done implicitly.
device_add will later need the reserved "id" property. Hotplugging a CPU
on s390x will then be: "device_add host-s390-cpu,id=cpu2,core-id=2".

breaks the migration compatibility.
