[PATCH] nouveau: fix build error on IA64

[Fengguang Wu]

I'm not sure if this is the best way, however it does fix the last 2
allmodconfig errors on IA64:

ERROR: "wmi_has_guid" [drivers/gpu/drm/nouveau/nouveau.ko] undefined!
ERROR: "wmi_evaluate_method" [drivers/gpu/drm/nouveau/nouveau.ko] undefined!
