We get 2 warnings when building kernel with W=1:
drivers/gpu/drm/nouveau/nvkm/subdev/volt/gk104.c:38:1: warning: no previous prototype for 'gk104_volt_get' [-Wmissing-prototypes]
drivers/gpu/drm/nouveau/nvkm/subdev/volt/gk104.c:51:1: warning: no previous prototype for 'gk104_volt_set' [-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'.
