[PATCH] fix:overlay: add missing header dependencies

[Baoyou Xie]

We get 1 warning when build kernel with W=1:
drivers/gpu/drm/nouveau/dispnv04/overlay.c:496:1: warning: no previous prototype for 'nouveau_overlay_init' [-Wmissing-prototypes]

In fact, this function is declared in disp.h, so this patch
add missing header dependencies
