drm/bridge: lt8912b: Add missing drm_bridge_attach call

Browse source 
[ Upstream commit f45acf7acf ]

The driver does not call drm_bridge_attach(), which causes the next
bridge to not be added to the bridge chain. This causes the pipeline
init to fail when DRM_BRIDGE_ATTACH_NO_CONNECTOR is used.

Add the call to drm_bridge_attach().
