cmhw: Add support for GPU-based color calibration

 * If the LiveDisplay kernel interface is not available, use our custom
   SurfaceFlinger transaction to set the color matrix using the GPU.
 * This is obviously not the preferred path as it has a significantly
   higher power cost than using the display hardware directly.
