drm/amd/display: Limit DCN32 8 channel or less parts to DPM1 for FPO
- Due to hardware related QoS issues, we need to limit certain
SKUs with less memory channels to DPM1 and above.
- At DPM0 + workload running, the urgent return latency can
exceed 15us (the expected maximum is 4us) which results in underflow
