[PATCH 2/2] drm/probe-helper: remove unused drm_connector_helper_get_modes_from_ddc()

[Jani Nikula <jani.nikula@xxxxxxxxx>]

Remove the unused drm_connector_helper_get_modes_from_ddc()
function. Most drivers should probably have this functionality split to
detect and get modes parts, so the helper is not the best abstraction.
