We get 2 warnings when build 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'.
