   V4:
     - Added missing powerzone-cells
     - Changed powerzone name to comply with the pattern property
   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
