From: Thierry Reding <treding@xxxxxxxxxx>
The GV11B's device tree bindings are the same as for GP10B, though the
GPU is not completely compatible, so all that is needed is a different
compatible string.

Changes in v3:
- document the "fuse" clock which needs to be enabled during the GPU
initialization
