Modified Files:
        src/sys/arch/arm/allwinner: awin_debe.c awin_hdmi.c awin_hdmiaudio.c
            awin_tcon.c awin_var.h

Log Message:
Turn off video output on WSDISPLAYIO_SVIDEO.
For LCD/LVDS, just stop the tcon0.
For HDMI, turn off tcon and hdmi (so that the monitor goes to sleeo)
if the audio output is inactive.
For this, add a lock-protected refcount in awin_hdmi, incremented when
audio and/or video is active.
Tested with an audio-enabled HDMI display.
