convert drm_atomic_helper_suspend/resume() to use
drm_mode_config_helper_suspend/resume().

exynos_drm_fbdev_suspend/resume can be removed
as drm_mode_config_helper_suspend/resume has
implement the same in generic way.

v2: Address Inki Dae's comment. Remove
    ret variable from both suspend/resume
    function.
