Test Patch for HDMI scrambling issues

Here is a test patch the disable the HDMI Scrambler CTS and Scrambler Reset
bits currently being set by the Linux driver. The QD980 reports HF1-13 passing,
but requires a manual (xrandr) mode change between Iterations. Use view video
feature to confirm scrambling is enabled and disabled correctly during mode
change.

Switching between 720x480 and 720x576 appears to work after the hot plug is
generated.
