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

+                This custom interface is needed (instead of using the generic
+                Linux user-space PCI mapping) because this space is protected
+                and cannot be accessed using PCI read.
