[PATCH 2/6] drm/amd/display: Use new DRM API where possible

From: "Leo (Sunpeng) Li" sunpeng.li@amd.com

To conform to DRM's new API, we should not be accessing a DRM object's internal state directly. Rather, the DRM for_each_old/new_* iterators, and drm_atomic_get_old/new_* interface should be used.

This is an ongoing process. For now, update the DRM-facing atomic functions, where the atomic state object is given.
