drm/exynos: added comments and code clean.
this patch adds the following comments and code clean. - add comment of exynos_drm_crtc_apply() call at page flip time. - add comment that when exynos_drm_fbdev_reinit() is called, why num_connector is 0 and also the framebuffers should be destroyed. - remove buf_off member from struct exynos_drm_overlay because this member isn't used anymore.
