PX30 SoCs feature an ARM Bifrost GPU.

Hello, this change is just adding basic GPU support, more work is
needed on the devfreq/opp side to be sure everything works and is
properly described. Hence, this proposal aims at describing the HW
block only, not its hability to change voltages/frequencies.

Thanks,
Miquèl
