It may be different on each target. Also, MDP5 doesn't have vertical limitation in one frame, as long as the pixel clock can be supported. This change obtains the maximum LM resolution from configuration table and treat it as the whole pipe's limitation for MDP5. The size limit on MDP4 is not changed.
