[PATCH 1/3] drm/msm/dpu: remove manual destruction of DRM objects

[Dmitry Baryshkov <dmitry.baryshkov@xxxxxxxxxx>]

Remove manual removal of DRM modesetting objects, it is done anyway by
the drm_mode_config_cleanup() called from msm_drm_uninit(). Other
MSM display drivers (MDP4, MDP5) do not manually destroy objects and
trust generic code to do it's work.
