Subject: [PATCH] drm/tegra: Convert drm_atomic_helper_suspend/resume()
convert drm_atomic_helper_suspend/resume() to use
drm_mode_config_helper_suspend/resume().
With this conversion, tegra_drm_fb_suspend() and
tegra_drm_fb_resume() wil not be used anymore.
Both of these functions can be removed.
Also, in tegra_drm struct's member state will not be
used anymore. So this can be removed forever.
Fixed one sparse warning.
