Subject: [PATCH v16 0/2] add debugfs to migration driver

Add a debugfs function to the migration driver in VFIO to provide
a step-by-step debugfs information for the migration driver.

Changes v15 -> v16
	Update the calling order of functions to maintain symmetry

Changes v14 -> v15
	Update the output status value of live migration.

Changes v13 -> v14
	Split the patchset and keep the vfio debugfs frame.

Changes v12 -> v13
	Solve the problem of open and close competition to debugfs.

Changes v11 -> v12
	Update loading conditions of vfio debugfs.

Changes v10 -> v11
	Delete the device restore function in debugfs.

Changes v9 -> v10
	Update the debugfs file of the live migration driver.

Changes v8 -> v9
	Update the debugfs directory structure of vfio.

Changes v7 -> v8
	Add support for platform devices.

Changes v6 -> v7
	Fix some code style issues.

Changes v5 -> v6
	Control the creation of debugfs through the CONFIG_DEBUG_FS.

Changes v4 -> v5
	Remove the newly added vfio_migration_ops and use seq_printf
	to optimize the implementation of debugfs.

Changes v3 -> v4
	Change the migration_debug_operate interface to debug_root file.

Changes v2 -> v3
	Extend the debugfs function from hisilicon device to vfio.

Changes v1 -> v2
	Change the registration method of root_debugfs to register
	with module initialization.
