media: rockchip: rga: Only set output CSC mode for RGB input
[ Upstream commit 0f879bab72f47e8ba2421a984e7acfa763d3e84e ]
Setting the output CSC mode is required for a YUV output, but must not
be set when the input is also YUV. Doing this (as tested with a YUV420P
to YUV420P conversion) results in wrong colors.
Adapt the logic to only set the output CSC mode when the output is YUV and
the input is RGB. Also add a comment to clarify the rationale.
