Naomi Luis e2de425bc4 Display: Set WAIT on primary and NO_WAIT on HDMI 
When queuing buffers using the overlay:
- Set the NO_WAIT flag for the HDMI channel.
- Set the WAIT flag for the primary channel.
- Queue the buffer on the HDMI first.
- Queue the buffer on the primary.
- Wait for the HDMI Vsync.
