Subject: [PATCH v2 22/35] drm/atomic-helper: Change parameter name of
 drm_atomic_helper_commit_hw_done()

drm_atomic_helper_commit_hw_done() signals hardware completion of 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.
