drm/bridge: rename drm_for_each_bridge_in_chain_scoped() to drm_for_each_bridge_in_chain()

drm_for_each_bridge_in_chain_scoped() was added in commit e46efc6a7d
("drm/bridge: add drm_for_each_bridge_in_chain_scoped()") to provide a
safer alternative to drm_for_each_bridge_in_chain().

Following commits converted all users to the _scoped variant.

Finally commit 2f08387a44 ("drm/bridge: remove
drm_for_each_bridge_in_chain()") removed the old
drm_for_each_bridge_in_chain() macro.

It's time to rename drm_for_each_bridge_in_chain_scoped() back to the
original name.
