Add a FIP driver hooked to debugfs 9p interface. This is an
abstraction of the FIP filesystem layer on top of a mass storage,
or memory block driver.

0ca3913dd8 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.
