[RFC PATCH v2 10/20] hw/usb/hcd-ohci: Mark the device with no migratable fields

[Philippe Mathieu-Daudé]

This device doesn'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.
