Subject: drm/nouveau/bios: make const arrays hwsq_signature and edid_sig static
Git-commit: 1a5c8164b335fb841fd9b41cd3d659de2f1c912b
Patch-mainline: v4.15-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

Don't populate arrays hwsq_signature and edid_sig on the stack but
instead make them static. Makes the object code smaller by over 190
bytes:

Before:
   text    data     bss     dec     hex filename
  35676    3312      64   39052    988c nouveau_bios.o

After:
   text    data     bss     dec     hex filename
  35319    3472      64   38855    97c7 nouveau_bios.o

(gcc version 7.2.0 x86_64)
