Nouveau - Sep 2016 - [PATCH 1/3] drm/nouveau: add missing header dependencies

We get a few warnings when building kernel with W=1:
drivers/gpu/drm/nouveau/nvkm/subdev/fb/sddr2.c:60:1: warning: no previous
prototype for 'nvkm_sddr2_calc' [-Wmissing-prototypes]
drivers/gpu/drm/nouveau/nvkm/subdev/fb/sddr3.c:69:1: warning: no previous
prototype for 'nvkm_sddr3_calc' [-Wmissing-prototypes]
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/fb/ram.h,
drivers/gpu/drm/nouveau/nvkm/subdev/volt/priv.h,
drivers/gpu/drm/nouveau/nvkm/core/firmware.h,
drivers/gpu/drm/nouveau/nvkm/engine/gr/nv50.h,
drivers/gpu/drm/nouveau/dispnv04/disp.h,
so this patch adds missing header dependencies.
