Subject: [PATCH 08/17] drm/nouveau/volt: add missing header dependencies

We get 3 warnings when building kernel with W=1:
drivers/gpu/drm/nouveau/nvkm/subdev/volt/gpio.c:35:1: warning: no previous prototype for 'nvkm_voltgpio_get' [-Wmissing-prototypes]
drivers/gpu/drm/nouveau/nvkm/subdev/volt/gpio.c:54:1: warning: no previous prototype for 'nvkm_voltgpio_set' [-Wmissing-prototypes]
drivers/gpu/drm/nouveau/nvkm/subdev/volt/gpio.c:71:1: warning: no previous prototype for 'nvkm_voltgpio_init' [-Wmissing-prototypes]

In fact, these functions are declared in
drivers/gpu/drm/nouveau/nvkm/subdev/volt/priv.h.
So this patch adds missing header dependencies.
