The DisplayPort helpers rely on some (__drm_atomic_helper_private_obj_duplicate_state, drm_kms_helper_hotplug_event) helpers found in files compiled by DRM_KMS_HELPER. Prior to commitd674858ff9("drm/display: Make all helpers visible and switch to depends on"), DRM_DISPLAY_DP_HELPER was only selectable so it wasn't really a big deal. However, since that commit, it's now something that can be enabled as is, and since there's no expressed dependency with DRM_KMS_HELPER, it can break too. Since DRM_KMS_HELPER is a selectable option for now, let's select it for DRM_DISPLAY_DP_HELPER.
