[PATCH v5 0/6] drm/atomic: track individual colorop updates

[Melissa Wen <mwen@igalia.com>]

This series aims to track updates for each individual color operation,
allowing the driver to react accordingly.

- Patches 1 and 2 make colorop update process more consistent and
  optimized by only keeping colorop states from active color pipelines.

- Patches 3 and 4 make lut1d_interpolation and lut3d_interpolation
  colorops correctly behave as mutable, handling their changes via
  drm_colorop_state.

- Finally, patches 5 and 6 track colorop updates of a given plane color
  pipeline by setting plane `color_mgmt_changed` flag, similar to what
  is done for tracking CRTC color mgmt property changes with CRTC
  `color_mgmt_changed` flag. The flag also tracks when a different color
  pipeline is set to a given plane. That way, the driver can react
  accordingly and update their color blocks.

It also fixes shaper/3D LUT updates when changing night mode settings on
gamescope with a custom branch that supports `COLOR_PIPELINE`:
