debugfs: add 9p device interface
The 9p interface provides abstraction layers allowing the software
that uses devices to be independent from the hardware.
This patch provides a file system abstraction to link drivers to their
devices and propose a common interface to expose driver operations to
higher layers. This file system can be used to access and configure a
device by doing read/write operations.
