Revert "drm/bridge: Fix a NULL pointer dereference in drm_atomic_bridge_chain_check()"
This reverts commit b18398c1 ("drm/bridge: Fix a NULL pointer dereference in drm_atomic_bridge_chain_check()"). Commit 6ed7e962 ("drm/bridge: Add a drm_bridge_state object") introduced a circular dependency between drm.ko and drm_kms_helper.ko which uncovered a misdesign in how the whole thing was implemented. Let's revert all patches depending on the bridge_state infrastructure for now.
