drm/amd/display: Add KUnit tests for update_config

Expose update_config() for KUnit and cover the NULL connector and NULL
dc_link early returns, the dpms_off removal path and the active path
that builds the display/link state and registers the connector. The
active path leaves the DTM TA uninitialized so add_display_to_topology()
returns early without touching firmware.
