Add a debugfs function to the hisilicon migration driver in VFIO to
provide intermediate state values and data during device migration.

When the execution of live migration fails, the user can view the
status and data during the migration process separately from the
source and the destination, which is convenient for users to analyze
and locate problems.

This patch was previously reviewed and added Reviewed-by: Jason Gunthorpe.

As the first version of this set of patches, I removed it and sent it again.

Thanks.
