Subject: [PATCH v3 2/5] arm64: dts: rockchip: Add powerzones definition for rock960
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
