PX30 SoCs feature an ARM Bifrost GPU.

Signed-off-by: Miquel Raynal miquel.raynal@bootlin.com ---

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
