drm/amd/display: Refactor output transfer function to stream
Refactor part 3 - Moving output transfer function from surface to stream
Split HWSS to program degamma and regamma separately.
Degamma should be dependent on input transfer function.
And Regamma should depend on the desired output transfer function.
