MDP planes can be implemented using different type of HW pipes, RGB/VIG/DMA pipes for MDP5 and RGB/VG/DMA pipes for MDP4. Each type of pipe has different HW capabilities such as scaling, color space conversion, decimation... Add a variable in plane data structure to specify the difference of each plane which comes from mdp5_cfg data and use it to differenciate the plane operation.
