video/drm: vop2: fix some csc parameters error
1. Fix the csc matrix. For YUV709L to YUV709L, YUV601L to
YUV601L, YUV2020L to YUV2020L, The csc matrix should be
identity matrix. For YUV601L to YUV70
video/drm: vop2: fix some csc parameters error
1. Fix the csc matrix. For YUV709L to YUV709L, YUV601L to
YUV601L, YUV2020L to YUV2020L, The csc matrix should be
identity matrix. For YUV601L to YUV709L, modeify the csc
matrix.
2. optimize the final calculation result. Use the new r2y
and y2r matrix for csc yuv2yuv and rgb2rgb case. A simple
round is used for csc yuv2yuv and rgb2rgb case for a more
precise result.
