On the debugfs framework of VFIO, register the debug function for the live migration driver of the hisilicon accelerator device.

You should put this all in its own file and not compile it when debugfs is turned off as well.
Here use this macro #ifdef CONFIG_DEBUG_FS to wrap the creation part of debugfs. Do you think it can be handled like this?
