Jon Hunter 18d1b1b536 gpu: nvgpu: Add abstraction layer for NVHost fence ...

In preparation for adding support for the upstream Host1x driver,
add a layer of abstraction for calling the NVHost fence APIs. This
provides a clean interface for calling the appropriate APIs for either
the downstream NVHost fence APIs or the upstream DMA fence and Host1x
APIs, depending on which is being used.
