2024-05-13drm/amd/display: Add left edge pixel for YCbCr422/420 + ODM pipe splitWenjing Liu2-5/+3
[WHY] Currently 3-tap chroma subsampling is used for YCbCr422/420. When ODM pipesplit is used, pixels on the left edge of ODM slices need one extra pixel from the right edge of the previous slice to calculate the correct chroma value. Without this change, the chroma value is slightly different than expected. This is usually imperceptible visually, but it impacts test pattern CRCs for compliance test automation. [HOW] Update logic to use the register for adding extra left edge pixel for YCbCr422/420 ODM cases.

2024-04-30drm/amd/display: use even ODM slice width for two pixels per containerWenjing Liu2-9/+2
[why] When optc uses two pixel per container, each ODM slice width must be an even number. [how] If ODM slice width is odd number increase it by 1.

[why] Move all optc files to unique folder optc. [how] creating optc repo in dc, and moved the dcnxx_optc.c and .h files into corresponding new folders inside the optc and cleared the linkage errors by adding relative paths in the Makefile.template.
