From: "Dr. David Alan Gilbert" <li...@treblig.org>
The last use of drm_atomic_helper_commit_planes_on_crtc() was removed
in 2018 by
commit 6c246b81f938 ("drm/i915: Replace call to commit_planes_on_crtc with
internal update, v2.")
Remove it.

- * drm_atomic_helper_commit_planes_on_crtc - commit plane state for a CRTC

- *
- * This function commits the new plane state using the plane and atomic helper
- * functions for planes on the specific CRTC. It assumes that the atomic state
- * has already been pushed into the relevant object state pointers, since this
- * step can no longer fail.
- *
- * This function is useful when plane updates should be done CRTC-by-CRTC
- * instead of one global step like drm_atomic_helper_commit_planes() does.
- *
- * This function can only be savely used when planes are not allowed to move
- * between different CRTCs because this function doesn't handle inter-CRTC
- * dependencies. Callers need to ensure that either no such dependencies exist,
- * resolve them through ordering of commit calls or through some other means.
