So far the dependency has been satisfied by the users selecting VIDEOMODE_HELPERS themselves (e.g. the Exynos and i.MX DRM drivers), which breaks as soon as a user does not, resulting in undefined references to of_get_drm_display_mode() at link time. Select VIDEOMODE_HELPERS from DRM_OF_DISPLAY_MODE_BRIDGE, so that the dependency is always satisfied.
