[PATCH v3 1/4] drm/i915/display: Copy color pipeline from plane in the primary joiner pipe

[Chaitanya Kumar Borah <chaitanya.kumar.borah@intel.com>]

When copying plane color state in a joiner configuration, use the plane in
the primary joiner pipe since it carries the pipeline number selected by
the user-space.

This assumes that all pipes in the joiner are symmetric in their plane
color capabilities.
