For all these "Remove ..." patches I think it'd be better to rewrite the
changed code to use atomic state for whatever it does directly and stop
using any of the legacy state (whether drm core or i915 legacy state). If
we do that conversion it's possible to review whether there's any cases
we're no longer checking. Trying to do that while we just rip out code
makes that harder.
hw state checker would then only compare hw state against atomic state,
and it would be the job of update_legacy_state and friends to make sure
atomic state matches up with legacy state.
