Subject: [PATCH 4/5] drm/solomon: Simplify get_modes() using DRM helper

The ssd130x_connector_get_modes function contains a manual implementation
to manage modes.

This pattern is common for simple displays, and the DRM core already
provides the drm_connector_helper_get_modes_fixed() helper for this exact
use case.
