[PATCH 3/3] drm: Fix references to drm_plane_helper_check_state()

[Geert Uytterhoeven]

As of commit a01cb8ba3f628293 ("drm: Move drm_plane_helper_check_state()
into drm_atomic_helper.c"), drm_plane_helper_check_state() no longer
exists, but is part of drm_atomic_helper_check_plane_state().

Interestingly, all these comments appeared only after the commit that
removed the function...

This is against next-20230602, which does not have the
drivers/gpu/drm/{ => renesas}/rcar-du move yet.

Biju: you're adding a new copy in
drivers/gpu/drm/renesas/rz-du/rzg2l_du_crtc.c
