27Description:	Initiates a SoC reset on the MHI controller.  A SoC reset is
28                a reset of last resort, and will require a complete re-init.
29                This can be useful as a method of recovery if the device is
30                non-responsive, or as a means of loading new firmware as a
31                system administration task.
