[PATCH] drivers/gpu/drm/nouveau/dispnv50/headc57d.c: mark headc57d_olut() as static

[zhaoxiao]

Fixes the following W=1 kernel build warning(s):

drivers/gpu/drm/nouveau/dispnv50/headc57d.c:173:1: warning: no previous prototype for ‘headc57d_olut’ [-Wmissing-prototypes]
headc57d_olut(struct nv50_head *head, struct nv50_head_atom *asyh, int size)

And no header file define a prototype for this function, so we should
mark it as static.
