Patch to fix drm_encoder_slave.h includes.

When doing an out-of-tree compile on the nouveau kernel module, recent GIT
versions fail to compile without patching for a couple reasons.  The first can
be fixed with the attached patch.

The second has to do with the fact that drivers/gpu/drm/nouveau/nouveau_drv.h
declares the prototype for nouveau_encoder_connector_get, which relies on the
type `struct nouveau_encoder*', defined in
drivers/gpu/drm/nouveau/nouveau_encoder.h.  However, nouveau_encoder.h needs
nouveau_drv.h for the type `struct nv04_output_reg'.  This circular dependency
causes compilation of nouveau_drv.c to fail.

Also, any reason the include guard for nouveau_encoder.h is called
__NOUVEAU_OUTPUT_H__?
