I added this map as a common file, so all the sub driver of the syscon can use it. In my view, it is ok to just add necessary offset, but lost a generic view of the whole syscon device. So I choose adding a full map. Regard, Inochi

The "top" system controller of CV18XX/SG200X exposes control register access for various devices. Add soc header file to describe it.
