drm/amd/display: Set default bits per channel
[Why] Bump into calcReducedBlankingTiming because of mode query failed. In this function, timing.displayColorDepth == DISPLAY_COLOR_DEPTH_UNDEFINED. Then req_bw == 0 because of bits_per_channel == 0. So decide edp link settings, use default RBRx1 for special timing. [How] Set default bits_per_channel is 8. Signed-off-by:Jing Zhou <Jing.Zhou@amd.com> Reviewed-by:
