drm/i915: Only enable DFP 4:4:4->4:2:0 conversion when outputting YCbCr 4:4:4
Let's not enable the 4:4:4->4:2:0 conversion bit in the DFP unless we're
actually outputting YCbCr 4:4:4. It would appear some protocol
converters blindy consult this bit even when the source is outputting
RGB, resulting in a visual mess.
