Add an Operating Performance Points table for the GPU to enable Dynamic Voltage & Frequency Scaling on the H6.
The voltage range is set with minival voltage set to the target and the maximal voltage set to 1.2V. This allow DVFS framework to work properly on board with fixed regulator.

That patch seems reasonable, why shouldn't we merge it?

All those nodes will create DTC warnings though.
