drm/msm/dpu: update bandwidth threshold check
Maximum allowed bandwidth has no dependency on the type of panel used. Hence, cleanup the code to use max_bw_high as the threshold value for bandwidth checks. Update the maximum allowed bandwidth as 6.8Gbps for SC7180 target. Signed-off-by: Krishna Manikandan <mkrishn@codeaurora.org> Signed-off-by: Rob Clark <robdclark@chromium.org>
