media: atomisp: add missing wait_prepare/finish ops

Without these ops the v4l2-compliance blocking wait test will fail.
These ops are required to ensure that when VIDIOC_DQBUF has to
wait for buffers to arrive, the queue lock is correctly released
and retaken. Otherwise the wait for a buffer would block all other
queue ioctls.
