drm/i915/display: Don’t use atomic state back-pointer to derive color pipeline

Browse source

Instead of relying on the plane_state->uapi.state back-pointer to reach
the intel_atomic_state inside intel_plane_color_copy_uapi_to_hw_state(),
accept the intel_atomic_state as an argument to make the dependency
explicit.

Update intel_plane_copy_uapi_to_hw_state() and its callers accordingly.
Call sites that do not have an atomic state available (e.g. legacy cursor
update and initial plane setup) pass NULL.

In such cases, skip color pipeline programming as there is no
corresponding atomic colorop state to consume.
