[09/29] drm/atomic-helper: Change parameter name of drm_atomic_helper_update_legacy_modeset_state()

Commit Message

drm_atomic_helper_update_legacy_modeset_state() updates all the legacy
modeset pointers a connector, encoder or CRTC might have with the ones
being setup by a given 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.
