MLK-20117 drm/imx/dcss: fix color issue when Adobe_ARGB gamut is used 

Adobe ARGB gamut was selected even if the output pipe pixel encoding was
YUV. That produced a pink tint on the screen.

This patch will make sure the Adobe ARGB gamut is selected only when the
output pipe pixel encoding is RGB.
