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

From: Baoyou Xie
Date: Mon Aug 29 2016 - 06:34:10 EST

We get 2 warnings when biuld kernel with W=1:
drivers/gpu/drm/nouveau/nvkm/engine/pm/base.c:75:1: warning: no previous prototype for 'nvkm_perfsig_find' [-Wmissing-prototypes]
drivers/gpu/drm/nouveau/nvkm/engine/pm/base.c:703:1: warning: no previous prototype for 'nvkm_perfsrc_new' [-Wmissing-prototypes]

In fact, these 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'.
