Add special mirroring modes for demonstration purposes.
Assume rotation of HDMI display is portait.
$ adb shell setprop persist.demo.hdmirotation portrait
Don't lock rotation while HDMI is plugged in.
$ adb shell setprop persist.demo.hdmirotationlock false
Hide secondary displays from apps but continue mirroring to them.
$ adb shell setprop persist.demo.singledisplay true
