[PATCH 11/29] drm/atomic-helper: Change parameter name of drm_atomic_helper_commit_planes()

[Maxime Ripard <mripard@xxxxxxxxxx>]

drm_atomic_helper_commit_planes() updates all planes 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.
