gpu: nvgpu: make os_fence_android_syncpt common

Browse Source 
The differences between sync_fence ("android sync") and dma_fence are
abstracted away by nvhost in the nvhost_fence interface. There is no
need to have separate android and dma os fences for syncpoints; unify
the general implementation so that it's always used when requested for
the build.
