Hi, Jason:
The purpose of this hisi_acc_vf_debug_restore function is to obtain the
migration status data of the migration device. It is a debug operation.
Just to obtain this status data, user need to complete the few steps
of live migration.
Therefore, it is a debug function here, not a self-test function.

Thanks,
Longfang.
