Several source files include drm_crtc_helper.h without needing it or only to get its transitive include statements; leading to unnecessary compile-time dependencies. Drop drm_crtc_helper.h where possible. v2: * update commit message (Sam) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Sam Ravnborg <sam@ravnborg.org> Acked-by: Jani Nikula <jani.nikula@intel.com> Acked-by: Alex Deucher <alexander.deucher@amd.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230116131235.18917-13-tzimmermann@suse.de
