s390x: add property adapter_routes_max_batch
To make virtio-ccw supports more that 64 virtqueues we will have to
increase ADAPTER_ROUTES_MAX_GSI which is currently limiting the number if
possible adapter routes. Of course increasing the number of supported
routes can break backwards migration.
Let us introduce a compatibility property adapter_routes_max_batch so
client code can use the some old limit if in compatibility mode and
retain the migration compatibility.
