gpu: nvgpu: create a wrapper over sync_fences
This patch constructs an abstraction to hide the sync_fence
functionality from the common code. struct nvgpu_os_fence acts as an
abstraction for struct sync_fence.
struct nvgpu_os_fence consists of an ops structure named nvgpu_os_fence_ops
which contains an API to do pushbuffer programming to generate wait
commands for the fence.
The current implementation of nvgpu only allows for wait method on a
sync_fence which was generated using a similar backend(i.e. either
Nvhost Syncpoints or Semaphores). In this patch, a
generic API is introduced which will decide the type of the underlying
implementation of the struct nvgpu_os_fence at runtime and run the
corresponding wait implementation on it.
This patch changes the channel_sync_gk20a's semaphore specific
implementation to use the abstract API. A subsequent patch will make
the changes for the nvhost_syncpoint based implementations as well.
