This results in the following build errors if DRM_ANALOGIX_DP is configured as module.
ERROR: "analogix_dp_start_video" [drivers/gpu/drm/bridge/analogix/analogix_dp_core.ko] undefined! ERROR: "analogix_dp_get_lane0_link_training" [drivers/gpu/drm/bridge/analogix/analogix_dp_core.ko] undefined!

[ and so on ]
It should probably be something like
analogix_dp-objs := analogix_dp_core.o analogix_dp_reg.o obj-$(CONFIG_DRM_ANALOGIX_DP) += analogix_dp.o
