ARM: dts: sun8i-s3: pinecube: Fix CSI DTC warnings

Our CSI endpoint trigger some DTC warnings due to the fact that we're
having a single endpoint that doesn't need any reg property, and since
we don't have a reg property, we don't need the address-cells and
size-cells properties anymore.

Fix those
