drm/amd/display: Calculate output_color_space after pixel encoding adjustment

Code in get_output_color_space depends on knowing the pixel encoding to
determine whether to pick between eg. COLOR_SPACE_SRGB or
COLOR_SPACE_YCBCR709 for transparent RGB -> YCbCr 4:4:4 in the driver.

v2: Fixed patch being accidentally based on a personal feature branch, oops!
