Debarshi Dutta 6fe9bb835b gpu: nvgpu: access channel_sync via public API
struct nvgpu_channel_sync is moved to a private header i.e.
channel_sync_priv.h present in common/sync/. All accesses to callback
functions inside the struct nvgpu_channel_sync in NVGPU driver is replaced by
the public channel_sync specific APIs.
