drm/amd/display: Set watermarks set D equal to A

Browse Source 
[Description]
- Since we do not use optimized watermark settings for MALL,
  set D = A
- PMFW uses Set D for d0i3.1, so driver should make D = A for the
  time being
- If we choose to optimize in the future we can set watermarks D
  correctly
