[Intel-gfx] [PATCH 1/7] drm/i915: Clean up DP/HDMI limited color range handling

From: Ville Syrjälä <ville.syrjala at linux.intel.com>
Currently we treat intel_{dp,hdmi}->color_range as partly user
controller value (via the property) but we also change it during
.compute_config() when using the "Automatic" mode. That is a bit
confusing, so let's just change things so that we store the user
property values in intel_dp, and only change what's stored in
pipe_config during .compute_config().
There should be no functional change.
