During suspend, HDMI clocks are still running and power
consumption is high. Usually HPD module is kept on even
when the cable is not connected to sense the cable
re-connect. But cable connect sense is not required when
the device is suspended. This change makes sure that HPD,
along with other HDMI modules, are totally shutdown during
suspend and there is no power consumption by HDMI.

until the free queue is completely exhausted. However, client can
deallocate buffers immediately after writeback_stop() is called, this
