Subject: [PATCH 17/17] drm/nouveau: mark symbols static where possible

We get 2 warnings when building kernel with W=1:
drivers/gpu/drm/nouveau/nouveau_display.c:96:1: warning: no previous prototype for 'nouveau_display_scanoutpos_head' [-Wmissing-prototypes]
drivers/gpu/drm/nouveau/nv10_fence.c:70:1: warning: no previous prototype for 'nv10_fence_context_new' [-Wmissing-prototypes]

In fact, both functions are only used in the file in which they are
declared and don't need a declaration, but can be made static.
So this patch marks these functions with 'static'.
