Subject: drm/sun4i: Implement drm_driver lastclose to restore fbdev console

From: Jonathan Liu <[email protected]>

commit 2a596fc9d974bb040eda9ab70bf8756fcaaa6afe upstream.

The drm_driver lastclose callback is called when the last userspace DRM client has closed. Call drm_fbdev_cma_restore_mode to restore the fbdev console otherwise the fbdev console will stop working.
