Add the powerzones description. This first step introduces the big,
the little as powerzone places.

   V3:
     - Remove GPU section as no power is available (yet)
     - Remove '#powerzone-cells' conforming to the bindings change
   V2:
     - Move description in the SoC dtsi specific file
   V1: Initial post
