From: Philipp Rossak <embed3d@xxxxxxxxx>
We are adding the devicetree binding for the PVR-SGX-544-115 gpu.
This driver is currently under development in the openpvrsgx-devgroup.
Right now the full binding is not figured out, so we provide here a
placeholder. It will be completed as soon as there is a demo
available.
The currently used binding that is used during development is more
complete and was already verifyed by loading the kernelmodule
successful.

This node doesn't have clocks, so I don't see how it'd work.
Better delay the introduction of the GPU node for this board until you
know it works.
