Dove GPU support

Hi Dove maintainers,

those 2 patches add support for the Vivante GPU. The binding has already been acked by the DT maintainers and is included in the pull request for the DRM driver. I hope you can pick those patches up for inclusion in 4.5.

Regards,
Lucas

Add DT support for the Vivante GC600 GPU on Marvell Dove platforms. These nodes default to being disabled unless a platform decides they should be enabled.

Hi Lucas,

Good timing! I was about to ask news about these pacthes.

They are both applied on mvebu/dt

Thanks,

Gregory
