[PATCH] drm/nouveau/gr: add missing header dependencies

[Baoyou Xie]

We get 2 warnings when build kernel with W=1:
drivers/gpu/drm/nouveau/nvkm/engine/gr/ctxnv50.c:255:1: warning: no previous prototype for 'nv50_grctx_fill' [-Wmissing-prototypes]
drivers/gpu/drm/nouveau/nvkm/engine/gr/ctxnv50.c:265:1: warning: no previous prototype for 'nv50_grctx_init' [-Wmissing-prototypes]

In fact, these functions are declared in gr/nv50.h, so this patch
add missing header dependencies
