[PATCH v3 3/9] drm/msm/dpu: drop dpu_format_populate_layout from dpu_plane_sspp_atomic_update

[Dmitry Baryshkov <dmitry.baryshkov@xxxxxxxxxx>]

The dpu_plane_prepare_fb() already calls dpu_format_populate_layout().
Store the generated layout in the plane state and drop this call from
dpu_plane_sspp_update().
