[PATCH v4 4/5] drm/bridge-connector: move to DRM_DISPLAY_HELPER module

From: Dmitry Baryshkov
Date: Mon Jul 15 2024 - 02:34:27 EST

drm_bridge_connector is a "leaf" driver, belonging to the display
helper, rather than the "CRTC" drm_kms_helper module. Move the driver
to the drm/display and add necessary Kconfig selection clauses.

Suggested-by: Maxime Ripard <mripard@xxxxxxxxxx>
