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 commit d674858ff979 ("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.
