video: tegra: dc: use side-by-side stereo HDMI mode
Add a config option to limit HDMI stereo 3D output to 74.25MHz pixel clock.
When this option is set,
substitute the frame pack stereo modes
for side-by-side (half) left-right stereo modes
to meet this pixel clock restriction.
By default, do not use it (use frame packed HDMI mode as usual).
