Remove Exynos specific framebuffer structure and

relevant functions.
 - it removes exynos_drm_fb structure which is a wrapper of
   drm_framebuffer and unnecessary two exynos specific callback
   functions, exynos_drm_destory() and exynos_drm_fb_create_handle()
   because we can reuse existing drm common callback ones instead.
