Subject: [PATCH 17/17] drm/i915: Remove wm_config from
dev_priv/intel_atomic_state
We calculate the watermark config into intel_atomic_state and then save
it into dev_priv, but never actually use it from there. This is
left-over from some early ILK-style watermark programming designs that
got changed over time.
