Subject: [PATCH v2 19/35] drm/bridge: Change parameter name of
 drm_atomic_bridge_chain_enable()

drm_atomic_bridge_chain_enable() enables all bridges affected by a new
commit. It takes the drm_atomic_state being committed as a parameter.

However, that parameter name is called (and documented) as old_state,
which is pretty confusing. Let's rename that variable as state.
