[PATCH v7 09/12] ARM: dts: sun6i: a31: add sgx gpu child node

[H. Nikolaus Schaller]

From: Philipp Rossak <embed3d at gmail.com>

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.
