[PATCH 17/18] hw/sparc64/sun4u: Mark devices with no migratable fields

[Philippe Mathieu-Daudé]

These devices don't have fields to migrate. Be explicit
by using vmstate_qdev_no_state_to_migrate.

Add a more descriptive comment to keep a clear separation
between static property vs runtime changeable.
