[RFC,v2,06/20] hw/arm/msf2-soc: Mark the device with no migratable fields

Commit Message

Philippe Mathieu-Daudé Jan. 17, 2021, 7:24 p.m. UTC

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.
