Subject: [PATCH 3/3] drm/nouveau: remove unused function

We get 1 warning when building kernel with W=1:
drivers/gpu/drm/nouveau/nvkm/engine/disp/sorg94.c:49:1: warning: no previous prototype for 'g94_sor_output_new' [-Wmissing-prototypes]

In fact, this function is called by no one and not exported,
so this patch removes it.
