drm/nouveau: fix build error without CONFIG_IOMMU_API
If CONFIG_IOMMU_API is n, build fails:
vers/gpu/drm/nouveau/nvkm/subdev/ltc/gp10b.c:37:9: error: implicit declaration of function dev_iommu_fwspec_get; did you mean iommu_fwspec_free? [-Werror=implicit-function-declaration]
spec = dev_iommu_fwspec_get(device->dev);
^~~~~~~~~~~~~~~~~~~~
iommu_fwspec_free
drivers/gpu/drm/nouveau/nvkm/subdev/ltc/gp10b.c:37:7: warning: assignment makes pointer from integer without a cast [-Wint-conversion]
spec = dev_iommu_fwspec_get(device->dev);
^
drivers/gpu/drm/nouveau/nvkm/subdev/ltc/gp10b.c:39:17: error: struct iommu_fwspec has no member named ids
u32 sid = spec->ids[0] & 0xffff;
Seletc IOMMU_API under config DRM_NOUVEAU to fix this.
