drm/amd/display: Use 1/8th DSC target bitrate precision for N4:2:2 and 4:2:0 formats
[why]
On at least some of the devices (e.g. Realtek scaler) we get a black screen if 1/16th
precision is used.
[how]
Work around it by reducing precision to 1/8th for N4:2:2 and 4:2:0 color formats. This
is a safe workaround and would have a very mild impact on the quality.
The issue is still to be root-caused and fixed correctly.
