msm_fb: display: add mdp clk rate calculation for low vbp For the panels that have low v_back_porch, if h/w FIR scaling is used, during vbp time, mdp clk should be fast enough to output a line from 4 input lines. MDP rate equation for very small scaling, e.g. 1 or 2 pixels' upscaling or downscaling cannot cover this case, where underruns are seen on those panels.
