video: tegra: host: Support external syncpt cbs
This far the nvhost driver has published interface for waiting
syncpoint values synchronously, however, we have need to do similar
waiting asynchronously (i.e. trigger event when certain syncpoint
value has been reached). This patch adds public function
nvhost_intr_register_notifier() that allows registering callbacks.
