gpu: nvgpu: implement poll() for semaphores
Add poll interface and control ioctls for waiting for GPU job completion
via semaphores.
Poll on a gk20a channel file waits for events from pending semaphore
interrupts (stalling) of that channel. New ioctls enable and disable the
events, and clear a single interrupt event so that next poll doesn't
wake up for it again.
