From: Thierry Reding <treding@xxxxxxxxxx>
The GPU found on NVIDIA Tegra194 SoCs is a Volta generation GPU called
GV11B.
Signed-off-by: Thierry Reding <treding@xxxxxxxxxx>

Changes in v3:
- mark the GPU as DMA coherent because that's enforced by the MSS
- add FUSE clock which is needed during GPU initialization
- enable GPU by default
