[PATCH 08/11] drm/i915: Use drm_fbdev_helper_client_unregister()

[Thomas Zimmermann <tzimmermann@suse.de>]

Implement struct drm_client_funcs.unregister with the helpers
drm_fbdev_helper_client_unregister() and remove the custom code
from the driver. The generic helper is equivalent in functionality.
